Answer:

77%

Explanation:

efficiency= work output/work input X 100%

e = 1,200j/ 1,550 j x100%

e = 1,200/1,550= 0.77

e = 0.77 x 100%

e = 77%

Answer:

The wavelength is 1.7cm

Explanation:

Given

See attachment for wave pattern

Required

What is the wavelength

To do this, we simply calculate the distance between successive waves (see attachment 2 for point A and B)

Using the ruler, points A and B are at:

[tex]A = 0.6cm[/tex]

[tex]B = 2.3cm[/tex]

So, the wavelength is:

[tex]\lambda = B - A[/tex]

[tex]\lambda = 2.3cm - 0.6cm[/tex]

[tex]\lambda = 1.7cm[/tex]

If approximated, the wavelength is:

[tex]\lambda \approx 2cm[/tex]

Answer:

The magnitude of the force required to move the electron through the given field is 2.203 N

Explanation:

Given;

The field strength of the electron, E = 1.375  x 10¹⁹ N/C

charge of electron, q = 1.602 x 10⁻¹⁹ C

The magnitude of the force required to move the electron through the given field is calculated as follows;

F = Eq

F = (1.375  x 10¹⁹ N/C) (1.602 x 10⁻¹⁹ C)

F = 2.203 N

Therefore, the magnitude of the force required to move the electron through the given field is 2.203 N

Answer:

E = 10078.32 J

Explanation:

Given that,

The weight of a window cleaner, F = 839.86 N

The window cleaner is cleaning windows on the 4th floor of a building at a height of 12 m.

We need to find the potential energy of the window cleaner. We know that the potential energy of an object is given by :

E = mgh

Put values,

E = 839.86 × 12

E = 10078.32  J

So, the window cleaner will have 10078.32  J of potential energy.

Answer:

Vibration means quickly moving back and forth (or up and down) about a point of equilibrium. ... Something that is vibrating may shake at the same time. If it vibrates in a regular way, it may produce a musical note because it can make the air vibrate. This vibration will send sound waves to the ear and to the brain.

Explanation:

Vibration, periodic back-and-forth motion of the particles of an elastic body or medium, commonly resulting when almost any physical system is displaced from its equilibrium condition and allowed to respond to the forces that tend to restore equilibrium.

Answer:

The correct option is (a).

Explanation:

Given that,

Current flowing through the resistor, R = 0.054 A

Resistance of the resistor, R = 15 ohms

We need to find the voltage. We know that, Ohm's law gives the relation between voltage, current and resistance i.e.

V = IR

Put all the values,

[tex]V=0.054 \times 15\\\\V=0.81\ V[/tex]

So, the required voltage is equal to 0.81 volts.

Answer:

B) change direction

Explanation:

Diffraction is the change of direction of waves that occurs when waves travel from one medium to another.

Reflection is the change of direction of waves when they bounce off of a barrier.

Refraction is the change of direction of waves that happens when waves pass from one medium to another.

Each of these are all the change in direction of waves.

Answer: 5V

Explanation: because 2 goes into 10, five times. Also I know it’s correct cuz I got it right in my quiz

The difference in potential between these two points is 5 V.

The electric potential between two points is the work done in taking a unit postive charge from one point to another.

The difference in potential between these two points is calculated as follows;

W = qV

V = W/q

V = 10/2

V = 5 V

Thus, the difference in potential between these two points is 5 V.

A 1,100 kg car is going at 22 m/s. Force is needed to stop it in 20

seconds is 1210 N.

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Using equation of motion,

v = u +  at

0 = 22 + a.20

a = 1.1 m/sec²

force = mass.acceleration

force = 1100.(1.1)

force = 1210 N.

Question:

A roller-coaster vehicle has a mass of 500 kg when fully loaded with passengers.  If the vehicle has a speed of 20.0 m/s at point A, what is the force exerted by the track on the vehicle at this point?

See attachment

Answer:

33700 Newton

Explanation:

Given

[tex]m = 500kg\\v = 24.0m/s\\r=10m[/tex]

First, we determine the forces acting on mass m.

They are: the force exerted by the track (Fn) and the weight of the vehicle (W)

So, the net force is:

[tex]F_{net} = F_n - W[/tex]

[tex]W=mg[/tex]

So:

[tex]F_{net} = F_n - mg[/tex]

Make Fn the subject

[tex]F_n = F_{net} + mg[/tex]

Fnet is calculated as:

[tex]F_{net} = F_c = \frac{mv^2}{r}[/tex] --- i.e. the centripetal force

So:

[tex]F_n = F_{net} + mg[/tex]

[tex]F_n = \frac{mv^2}{r} + mg[/tex]

[tex]F_n = \frac{500 * 24^2}{10} + 500 * 9.8[/tex]

[tex]F_n = 28800 + 4900[/tex]

[tex]F_n = 33700N[/tex]

Answer: The correct answer is A). Animal burrow because burrow fossils represent the preserved byproducts of behavior rather than physical remains, they are considered a kind of trace fossil. One common kind of burrow fossil is known as Skolithos, and the similar Trypanites, Ophiomorpha and Diplocraterion.

Animal burrow is  an example of a trace fossil.

The preserved remnants of plants and animals that were submerged in sediments like sand and mud beneath ancient seas, lakes, and rivers are known as fossils. Any preserved sign of life that is typically older than 10,000 years is considered a fossil.

After death, soft body parts degrade quickly, while hard body parts, including bones, shells, and teeth, can be replaced by minerals that solidify into rock. Soft components like feathers, ferns, or other signs of life, such footprints or faeces, may also be preserved in extremely rare circumstances. Both less familiar fossils like ammonites and trilobites as well as microscopic-sized ones like single-celled foraminifera or pollen grains can be found in the remains.

A trace fossil, also known as an ichnofossil, is a record of biological activity preserved in the fossil record but without the actual preserved plant or animal remains. Contrasting with body fossils, which are the preserved remains of portions of an organism's body that were typically modified by later chemical activity or mineralization, are trace fossils. Ichnology, the study of such trace fossils, is the field of study of iconologists.

Explanation:

Given that,

Vertical height, h = 2.31 m

We need to find the speed at the bottom of the slide. Let the speed be v. We can find it using the conservation of energy such that,

[tex]\dfrac{1}{2}mv^2=mgh\\\\v=\sqrt{2gh}[/tex]

Put all the values,

[tex]v=\sqrt{2\times 9.8\times 2.31} \\\\v=6.72\ m/s[/tex]

So, her speed at the bottom of the slide is equal to 6.72 m/s.

Answer:

Heavy rain, extreme weather conditions, humid, water spouts, tornadoes, heavy lightening.

Explanation:

Swampy areas are a transition area formed where water and dry lands tend to meet. Swampy areas are actually forested areas with contains moist and humid weather conditions which has necessitated the wet soil around such an environment.

Florida is a very typical example of a weather that supports the creation of swampy areas due to its humid, heavy rains, water spouts,turnadoes etc and other extreme weather conditions.
