Astrongman applies a constant force of 2000 n to a car of mass 1000 kg, which is initially at rest. (a) what is the acceleration of the car? (b) how far does the car move in 5 s?

(a) Acceleration

(b) Distance s = 25 m

Explanation:

We have given constant force F = 2000 N

Mass of the car = 1000 kg

(a) From newton's law we know that F = ma

So

(b) Tine is given as t = 5 sec

As the car is initially at rest so initial velocity u = 0 m/sec

From second equation of motion

So

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
