Answer:

As the earth rotates, it tries to drag/bring the tidal bulges with it. When a large amount of friction is applied, the earth spin will gradually and slow down but not all the way down.

Answer:

If the Earth spun slower the rate of tides will be higher because the moon will start revolving faster tan the Earth, creating more tides as the moon will revolve more around the Earth in a month.

The velocity of the car after 6.9 s if its acceleration is 1.5 m/s² due south would be  10.35 meters / seconds.

There are three equations of motion given by  Newton

v = u + at

S = ut + 1/2×a×t²

v² - u² = 2×a×s

Note that these equations are only valid for a uniform acceleration.

As given in the problem we have to find the velocity of the car we have to find the velocity of the car  after 6.9 s if its acceleration is 1.5 m/s² due south,

The acceleration of the car = 1.5 m/s²

The time taken by the car = 6.9 seconds

By using the first equation of the motion,

v = u + at

v = 0 + 1.5*6.9

v = 10.35 meters / seconds

Thus, the velocity of the car after 6.9 s, if its acceleration is 1.5 m/s² due south, would be  10.35 meters / seconds.

Explanation:

The person's weight is equal to 705.6 N when the mass at sea level is 72 kg.

The weight of a body can be defined as the force acting on the body due to gravity. Weight is a vector quantity if the gravitational force is working on the object.

The unit of the weight is that of force, which (S.I. unit) is Newton. A body with a mass of one Kg has a weight of 9.8 N on the surface of the Earth or on the seal level.

The mathematical equation to determine the weight of an object is written as follows:

W = mg

Given the mass of the person, m = 72 Kg

The acceleration due to gravity on the person, g = 9.8 m/s²

The weight of the person on the earth will be equal to:

W = 72 Kg × 9.8 m/s²

W = 705.6 N

Therefore, the weight of the person is 705.6 N.

Answer:

At least [tex]2\; \rm m[/tex].

Explanation:

The torque [tex]\tau[/tex] that a force exerts on a lever is equal the product of the following:

[tex]\tau = F\cdot r \cdot \sin\theta[/tex].

The force in this question is (at most) [tex]50\; \rm N[/tex]. That is: [tex]F = 50\; \rm N[/tex].

[tex]\sin \theta[/tex] is maximized when [tex]\theta = 90^\circ[/tex]. In other words, the force on the door gives the largest-possible torque when that force is applied perpendicular to the door. When [tex]\theta = 90^\circ\![/tex], [tex]\sin \theta =1[/tex].

If the force here is applied at a distance of [tex]r[/tex] meters away from the hinge (the fulcrum of this door,) the torque generated would be:

[tex]\begin{aligned}\tau &= F \cdot r \cdot \sin \theta \\ &= (50\, r)\; \rm N \cdot m\end{aligned}[/tex].

That torque is supposed to be at least [tex]100\; \rm N\cdot m[/tex]. That is:

[tex]50\, r \ge 100[/tex].

[tex]r \ge 2[/tex].

In other words, the force needs to be applied at a point a minimum distance of [tex]2\; \rm m[/tex] away from the hinge of this door.

(a) The minimum speed required for the ball to clear the net is 26.3 m/s.

(b) The horizontal distance of the ball when it clears the net is 11.3 m

(c) The total time spent in the air by the ball is 1 s.

The time of motion of the tennis ball is calculated by using the following kinematic equation as shown below;

[tex]h = h_0 + v_0_yt - \frac{1}{2} gt^2\\\\0.9 = 2.5+ 0 - \frac{1}{2} (9.8) t^2\\\\0.9 = 2.5 - 4.9t^2\\\\4.9t^2 = 1.6\\\\t^2 = \frac{1.6}{4.9} \\\\t^2 = 0.327\\\\t = \sqrt{0.327} \\\\t = 0.57 \ s[/tex]

The minimum speed of the ball is calculated as follows;

[tex]v_x = \frac{X}{t} \\\\v_x = \frac{15}{0.57} \\\\v_x = 26.3 \ m/s[/tex]

The time of motion from top of the high net is calculated as follows;

[tex]t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 0.9}{9.8} } \\\\t = 0.43 \ s[/tex]

Horizontal range = 0.43 x 26.3 = 11.3 m

Total time in air = 0.57 s + 0.43 s = 1.0 s

The value is [tex]E_i = 1.5596 *10^{-18} \ J[/tex]

Explanation:

From the question we are told that

The wavelength is [tex]\lambda = 48.2 nm = 48.2 *10^{- 9 }\ m[/tex]

The velocity is [tex]v = 2.371*10^6 \ m/s[/tex]

The mass of electron is [tex]m_e = 9.109*10^{-31} \ kg[/tex]

Generally the energy of the incident light is mathematically represented as

[tex]E = \frac{h * c}{\lambda}[/tex]

Here c is the speed of light with value [tex]c = 3.0 *10^{8} \ m/s[/tex]

h is the Planck constant with value [tex]h = 6.62607015 * 10^{-34 } J\cdot s[/tex]

So

[tex]E = \frac{6.62607015 * 10^{-34 }* 3.0 *10^{8}}{48.2 *10^{- 9 }}[/tex]

=> [tex]E = 4.12 *10^{-18} \ J [/tex]

Generally the kinetic energy is mathematically represented as

[tex]E_k = \frac{1}{2} * m_e * v^2[/tex]

=> [tex]E_k = \frac{1}{2} * 9.109*10^{-31} * (2.371*10^6 )^2[/tex]

=> [tex]E_k = 2.56 *0^{-18} \ J [/tex]

Generally the ionization energy is mathematically represented as

[tex]E_i = 4.12 *10^{-18} - 2.56 *0^{-18}[/tex]

Answer: sorry here’s the answers, I didn’t feel like typing it all

Explanation:

The correct answer to the 5 questions are;

1) Option A; The current stays the same throughout the circuit.

2) Option A;  The current will stay the same at 1 amp after passing through both resistors.

3) Option C; R1: 12 V, R2: 12 V

4) Option A; I1 is equal to I2

5) Option C; The sum of the current flowing in is equal to the sum of current flowing out.

1) In an electrical circuit, usually as current moves through each component, it stays the same. Thus, option A is correct.

2) Formula for current is;

I = V/R

We are told that there are two resistors in series each having a resistance of 5Ω. Thus; Total resistance = 5 + 5 = 10 Ω.

Thus; Current = 10/10 = 1 A.

The current will stay same at 1 A after passing through both resistors.

3) From the circuit we are given, we see that the Voltage is 12 V. Now, the same voltage would be transmitted through both resistor R1 and R2.

Option C is correct

4) The current splits upon passing resistor 1 and as such it means the current I2 going through the second resistor would be the same. Thus; I1 = I2.

5) Kirchoff's junction rule states that all the incoming currents to a particular junction must be equal to sum of all currents going out of that same junction. Thus, option C is correct.

Answer:

The amount of heat required is [tex]H_t = 1.37 *10^{6} \ J [/tex]

Explanation:

From the question we are told that

The mass of water is [tex]m_w = 20 \ ounce = 20 * 28.3495 = 5.7 *10^2 g[/tex]

The temperature of the water before drinking is [tex]T_w = 3.8 ^oC[/tex]

The temperature of the body is [tex]T_b = 36.6^oC[/tex]

Generally the amount of heat required to move the water from its former temperature to the body temperature is

[tex]H= m_w * c_w * \Delta T[/tex]

Here [tex]c_w [/tex] is the specific heat of water with value [tex]c_w = 4.18 J/g^oC [/tex]

So

[tex]H= 5.7 *10^2 * 4.18 * (36.6 - 3.8)[/tex]

=> [tex]H= 7.8 *10^{4} \ J [/tex]

Generally the no of mole of sweat present mass of water is

[tex]n = \frac{m_w}{Z_s}[/tex]

Here [tex]Z_w[/tex] is the molar mass of sweat with value

[tex]Z_w = 18.015 g/mol[/tex]

=> [tex]n = \frac{5.7 *10^2}{18.015}[/tex]

=> [tex]n = 31.6 \ moles [/tex]

Generally the heat required to vaporize the number of moles of the sweat is mathematically represented as

[tex]H_v = n * L_v[/tex]

Here [tex]L_v[/tex] is the latent heat of vaporization with value [tex]L_v = 7 *10^{3} J/mol[/tex]

=> [tex]H_v = 31.6 * 7 *10^{3} [/tex]

=> [tex]H_v = 1.29 *10^{6} \ J [/tex]

Generally the overall amount of heat energy required is

[tex]H_t = H + H_v[/tex]

=> [tex]H_t = 7.8 *10^{4} + 1.29 *10^{6}[/tex]

=> [tex]H_t = 1.37 *10^{6} \ J [/tex]

The SPEED of a car on the highway is 75 mph.

(You're correct on #6.)

Answer:

The Basic Concept

When we look at an object at rest, we say that it is in equilibrium since all the forces being applied on it, cancel out

now, if one of the force was slightly more than the other one in the same case. The object will start to move and NOT be in equilibrium

BUT

if an object is in a vacuum and moving on a frictionless surface, the object will attain equilibrium after some seconds since it will be moving with constant speed and all the forces acting on it will be equal

Hence, if the object is accelerating. we can say with surety that the object is not is equilibrium since from the second law of motion,

F = ma ; when a is a non-zero value, there is definitely some net force being applied on the object

Looking at the given case

in the question, we are given that the object is 'accelerating'  upwards

we proved above that if an object is accelerating, there is some net force on that object and hence the object is NOT in equilibrium

Since the object is accelerating, from the second law of motion:

F = ma; m cannot be zero and if a is a non-zero value as given in the question, there is definitely some net force on the object

Since there is some force being applied on the object, the object is NOT in equilibrium

Conclusion

Since we found that the object is NOT in equilibrium and that there is some net force on the object,

The first option is correct

The heat transfer takes place from the Ice to lemonade (ice → lemonade).

The term “heat transfer” refers to the movement of heat. The flow of heat across a system's boundary is due to a temperature differential between the system and its surroundings.

When a temperature difference exists between states of matter, heat transfer happens solely in the direction of decreasing temperature, that is, from a hot object to a cold item.

The temperature of ice is increasing while the lemonade is decreasing. Heat transfer happens solely in the direction of decreasing temperature,

Hence, the heat transfer takes place from the Ice to lemonade (ice → lemonade.
