What is the potential energy of a spring that is compressed 0.65 m by a 25 kg block if the spring constant is 95 n/m?

Question Parameter(s):

is compressed 0.65 m by a 25 kg block

if the spring constant is 95 n/m

Generally, the equation for the potential energy is mathematically given as

PE = mgh

Therefore

P.E=0.5 kx^2

P.E= 0.5 x 95 x (0.65)^2

P.E= 20 J

In conclusion, The potential energy of a spring

P.E= 20 J

Answers

Answer:

1/2 M V^2 = .1 M g H where 10% of PE goes into KE

V^2 = .2 g H = .2 * 9.8 * (2100 - 1600) = 980 m^2 / s^2

V = 31.1 m/s increase in speed during descent

1 km / hr = 1000 m / 3600 sec = .278 m/s

V = 31.1 m/s / (.278 m/s / km /hr)= 112 km/hr

After encountering another ‘syntax error’ a disgruntled programmer throws a mouse perpendicular to the ground and it explodes into 3 pieces. A 100 g piece travels at 1.2 m/s, and a 30 g piece travels at 0.80m/s. The third piece flies off at a speed of 0.75 m/s. If the angle between the first two pieces is 120 degrees calculate the momentum and direction of the third piece with respect to the 100 g piece.

Answers

The momentum and direction of the third piece with respect to the 100 g piece is 0.11 kgm/s at 11 degrees.

Conservation of linear momentum

The momentum and direction of the third piece with respect to the 100 g mass is determined by applying the principle of conservation of linear momentum.

Pi = Pf

where;

Pi is initial momentumPf is final momentum

0 = P₁ + P₂ + P₃

where;

P₁ is final momentum of the first pieceP₂ is final momentum of the second pieceP₃ is final momentum of the third piece

-P₃ = P₁ + P₂

-P₃x = P₁cosθ + P₂Cosθ --(1)

-P₃y = P₁sinθ + P₂sinθ --(2)

-P₃x = (0.1 x 1.2 x cos0) + (0.03 x 0.8 x cos120)

-P₃x = 0.12 - 0.012

-P₃x = 0.108 kgm/s

P₃x = -0.108 kgm/s

-P₃y = (0.1 x 1.2 x sin0) + (0.03 x 0.8 x sin120)

-P₃y = 0.0208 kgm/s

P₃y = -0.0208 kgm/s

Resultant momentum of third piece

[tex]P_3 = \sqrt{P_3x^2 + P_3y^2} \\\\P_3 = \sqrt{(-0.108)^2 + (-0.0208)^2} \\\\P_3 = 0.11 \ kgm/s[/tex]

Direction of third piece

[tex]tan \ \theta = \frac{P_3y}{P_3x} \\\\\theta = tan^{-1} (\frac{P_3y}{P_3x} )\\\\\theta = tan^{-1} (\frac{-0.0208}{-0.108} )\\\\\theta = 11\ ^0[/tex]

with respect to 100 g, direction of third piece is 11⁰

Electromagnetic radiation is a type of energy that is transmitted in incident photons as both magnetic and electric waves.

Electromagnetic radiation has a spectrum with varying wavelengths and frequencies, which gives it different properties.

Electromagnetic radiation is a type of energy that travels in packets of energy called photons as both electrical and magnetic waves.

Wave-particle duality is the name given to this phenomenon. This is a notion that defines how a wave behaves whether it behaves like particles, waves, or both particles and waves.

12/20 = I = .6 A

Answer:

a) 0.60 A

Explanation:

Given that,

→ Potential difference (V) = 12 V

→ Resistance (R) = 20 Ω

→ Current (I) = ?

Formula we use,

→ I = V/R

Let's solve the problem,

→ I = V/R

→ I = 12/20

→ [ I = 0.60 ]

Hence, option (a) is the answer.

Answers

As the charges’ distance increase, there is a weaker force of attraction between them hence the electrostatic force decreases as distance increases. It increase by 4 (times 4) so the force will decrease by 4 making the answer

Answers

Answer:

Its B

Explanation:

Its B because i said its B alright cool bet

Second and third class levers are differentiated by the location of the load. The correct option is b.

The position of the weight in relation to the fulcrum distinguishes second-class levers from third-class levers.

The load is situated in a second-class lever halfway between the fulcrum and the applied force. The effort is placed between the fulcrum and the load in a third-class lever.

The mechanical advantage and the way these levers magnify force or motion depend on where the load is placed in relation to the fulcrum.

Thus, the correct option is b.

The interior of a refrigerator has a surface area of 4.3 m2 . It is insulated by a 3.6 cm thick material that has a thermal conductivity of 0.0303 J/m · s ·◦ C. The ratio of the heat extracted from the interior to the work done by the motor is 6.3% of the theoretical maximum. The temperature of the room is 44.2◦C, and the temperature inside the refrigerator is 9.2 ◦C. Determine the power required to run the compressor.
Answer in units of W

Answers

Power is the ratio of the heat entered into the refrigerator to the coefficient of performance of the refrigerator. The power required to run the compressor in Watts is 249.149 W.

What is Power?

Power is the ratio of the heat entered into the refrigerator to the coefficient of performance of the refrigerator.

Given the surface area of the interior of the refrigerator is

A= 4.3 m ²

The refrigerator is insulated by a material of thickness

t =3.6 cm =0.036 m

The thermal conductivity of insulating material is

k =0.0300 J/m-s

The change in temperature inside the refrigerator and room temperature is

dT= (273.15 + 44.2) -(273.15 + 9.2) =35 K

The rate of heat entered the refrigerator.

[tex]Q=\frac{k\times A\times dT}{t}[/tex]

Substituting value into the equation, we get

Q =126.67 W

The coefficient of performance of the refrigerator is

[tex]COP=\dfrac{(273.15+9.2)}{(273.15+44.2)-(273.15+9.2)}[/tex]

COP = 8.07

As, work done by the motor is 6.3% of the theoretical maximum,

[tex]\dfrac{6.3\times8.07}{100} =0.50841[/tex]

The power required to run the compressor will be

[tex]P=\dfrac{126.67}{0.50841} =249.149\:\rm W[/tex]

The power required to run the compressor is 249.149 W
