The acceleration is 4 m/s² in the direction of motion

Explanation:

A car speeds up from rest to +16 m/s in 4 s

To find the acceleration:

1. Find the best rule contains initial velocity "u", final velocity "v", time "t"

  and acceleration "a"

2. Substitute the values of u , v and t in the rule

3. Find the acceleration a

→ v = u + a t

→ u = 0 m/s , v = + 16 m/s , t = 4 seconds

→ 16 = 0 + a(40

→ 16 = 4 a

Divide both sides by 4

→ a = 4 m/s² in the direction of motion

The acceleration is 4 m/s² in the direction of motion

To maximize the percentage of the power from the emf of a battery that is delivered to a device, what should the internal resist
Simora [160]

To maximize the power delivered to load, we should minimize the internal resistance which means option A is correct.

<h3>What is the relationship between the power and the internal resistance?</h3>

Power  can be  delivered to the internal resistance of a battery, but in a case whereby there is a decrease in the internal resistance will bring about the decrease in the  lost power  as well as the  increase in  the percentage of the power delivered to the device.

In this case, To maximize the power delivered to load, we should minimize the internal resistance

Therefore, Option A is correct.

What energy transformation is performed by a radio ?
ElenaW [278]

why was my answer taken off? There is no way to show evidence for this but ig I can explain. The electrical energy is what is used to power the radio so it works, then the energy is used to catch radio waves which makes sound energy. So the answer is C, electrical energy to sound energy

Two motors in a factory are running at slightly different rates. One runs at 825.0 rpm and the other at 786.0 rpm. You hear the
mixas84 [53]

Answer:

T=1.54s

Explanation:

From the question we are told that:

Speed of Motor 1 \omega_1=825rpm=>2 \pi 13.75

Speed of Motor 2 \omega_1=786rpm=>2 \pi 13.1

Therefore

Frequency of Motor 1 f_1=13.75

Frequency of Motor 2  f_2= 13.1

Generally the equation for Time Elapsed is mathematically given by

T=\frac{1}{df}

Where

df=f_1-f_2

df=13.75-13.1

df=0.65Hz

Therefore

T=\frac{1}{65}

T=1.54s
