A car accelerates down a level highway. What is the force in the direction of motion that accelerates the car?

Physics

Answer: The force of reaction force of the ground accelerates the car on a level road.

Explanation:

When the wheels apply tractive force on the wheels by applying torque that is generated by engine  of the car, the wheels in contact with the road tend to move backwards at the point of contact thus exerting a force in the direction opposite to the motion of the car. Now according to Newton's third law an equal and opposite forces act on the car which tend to accelerate the car in the direction of motion.

What is the total resistance of the circuit? (must include unit - ohms) I WILL GIVE BRAINLIEST!
ICE Princess25 [194]

Answer: 4 ohms

Explanation:

For parallel connection we use this formula

R=equivalent resistance

R1=24 ohms

R2=8 ohms

R3=12 ohms

1/R=1/R1 + 1/R2 + 1/R3

1/R=1/24 + 1/8 + 1/12

1/R=(1x1+3x1+2x1) ➗ 24

Cross multiplying we get

24x1=(1x1+3x1+2x1) x R

24=(1+3+2) x R

24=6xR

Divide both sides by 6

24 ➗ 6=6xR ➗ 6

4=R

R=4 ohms

If a net force of 800n is acting on an object with a mass of 60kg. What would be the objects accelerations
aivan3 [116]

Answer: 13.33 m/s^2

Explanation:

Force is the product of mass of an object and its acceleration.

i.e Force = Mass x Acceleration

Since Force on object = 800N

Mass of object = 6Kg

Acceleration = ?

Then, Force = Mass x Acceleration

800N = 60Kg x Acceleration

Acceleration = (800N/60kg)

Acceleration = 13.33 m/s^2 (The unit of acceleration is metre per second square)

Thus, the objects accelerations is 13.33 m/s^2
