A device that uses electricity and magnetism to create motion is called a "Motor" (which converts electric energy into mechanical energy) & <span>In a reverse process, a device that uses motion and magnetism can be used to create "Electromagnetism".

In short, 1st Blank = Motor
2nd Blank = Electromagnetism 

Hope this helps!</span>

Answer:

1. motor

2. electricity

Explanation:

A motor uses electromagnetism or electricity and magnetism to create motion. A motor converts electric energy into mechanical energy.

On the other hand, the reverse process of using motion and magnetism will create electricty. It will convert the mechanical energy to electrical energy. And the machine that does it is called a generator.

A series combination of two resistors, 7.25 ω and 4.03 ω, is connected to a 9.00 v battery.
almond37 [142]

a. 11.28\Omega

The equivalent resistance of a series combination of two resistors is equal to the sum of the individual resistances:

R_{eq}=R_1 + R_2

In this circuit, we have

R_1 = 7.25 \Omega\\R_2 = 4.03 \Omega

Therefore, the equivalent resistance is

R_{eq}=7.25 \Omega + 4.03 \Omega=11.28 \Omega

b. 5.8 V, 3.2 V

First of all, we need to determine the current flowing through each resistor, which is given by Ohm's law:

I=\frac{V}{R_{eq}}

where V = 9.00 V and R_{eq}=11.28 \Omega. Substituting,

I=\frac{9.00 V}{11.28 \Omega}=0.8 A

Now we can calculate the potential difference across each resistor by using Ohm's law again:

V_1 = I R_1 = (0.8 A)(7.25 \Omega)=5.8 V

V_2 = I R_2 = (0.8 A)(4.03 \Omega)=3.2 V

Identify the relationship between strong forces and electric forces in the nucleus.
Triss [41]

Answer:

C

Explanation:

The strong force holds together quarks, the fundamental particles that make up the protons and neutrons of the atomic nucleus, and further holds together protons and neutrons to form atomic nuclei. As such it is responsible for the underlying stability of matter.

9. A car driver brakes gently. Her car slows down front --
sleet_krkn [62]

Answer:

9) This is a case of deceleration

10)-0.8 ms-2

b) acceleration is the change in velocity with time

11)

a) 100 ms-1

b) 100 seconds

12) 10ms-1

13) more information is needed to answer the question

14) - 0.4 ms^-2

15) 0.8 ms^-2

Explanation:

The deceleration is;

v-u/t

v= final velocity

u= initial velocity

t= time taken

20-60/50 =- 40/50= -0.8 ms-2

11)

Since it starts from rest, u=0 hence

v= u + at

v= 10 ×10

v= 100 ms-1

b)

v= u + at but u=0

1000 = 10 t

t= 1000/10

t= 100 seconds

12) since the sprinter must have started from rest, u= 0

v= u + at

v= 5 × 2

v= 10ms-1

14)

v- u/t

10 - 20/ 25

10/25

=- 0.4 ms^-2

15)

a=v-u/t

From rest, u=0

8 - 0/10

a= 8/10

a= 0.8 ms^-2
