Answer:

It's A

Explanation:

I & II Both seismic waves (that cause earthquakes) and sound waves (which sonar uses) can be compressed because they are longitudinal. All other wave types are electromagnetic waves and cannot be compressed.

Use F = 1/T as your basis:

DaniilM [7]

Frequency=60Hz

$\\ \rm\rightarrowtail \nu=\dfrac{1}{T}$

$\\ \rm\rightarrowtail T=\dfrac{1}{\nu}$

$\\ \rm\rightarrowtail T=\dfrac{1}{60}$

$\\ \rm\rightarrowtail T=1.67\times 10^{-4}s$

$\\ \rm\rightarrowtail T=16.7\times 10^{-3}s$

$\\ \rm\rightarrowtail T=16.7ms$

A solar panel is used to recharge a battery. The solar panel produces 0.80 W of electrical power. The panel is 20% efficient. Wh

Vlad [161]

Answer:

Input power, Ip = 4 Watts

Explanation:

Given the following data;

Power output = 0.8 Watts

Efficiency = 20%

To find the power input of the sunlight onto the solar panel;

Mathematically, the efficiency of a machine is given by the formula;

$Efficiency = \frac {Out-put \; power}{In-put \; power} * 100$

Substituting into the formula, we have;

$20 = \frac {0.8}{Ip} * 100$

$20 = \frac {80}{Ip}$

Cross-multiplying, we have;

$20Ip = 80$

$Ip = \frac {80}{20}$

Input power, Ip = 4 Watts

How does displacement, acceleration, time, and velocity affect motion?

Softa [21]

Answer:

The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.

A 25 newton force applied on an object moves it 50 meters. The angle between the force and displacement is 40.0°. What is the va

zloy xaker [14]

Answer:

The value of work being done on the object is 958J.

Explanation:

Work done is equal to force multiply by distance, but when the angle is between the force and distance work done=Force (cos theta) × distance

Work done = Force(cos theta) × distance

Work done = 25N(cos 40.0°) × 50m

Work done = 25N(0.7660) × 50m

Work done = 19.15N × 50m

Work done = 957.5J = 958J

Therefore the value of work being done on the object is 958J.
