Work with your units:

1 watt-hour = 1 (joule/second) · (hour) = 1 (joule-hour / second)

(1 joule-hour/sec) · (3600 sec/hour) = 3600 joules

So 1 watt-hour = 3,600 joules

A car accelerates for 10 seconds. During this time, the angular
bagirrra123 [75]

Answer:

the angular acceleration of the car is 1.5 rad/s²

Explanation:

Given;

initial angular velocity, \omega_i = 10 rad/s

final angular velocity, \omega_f = 25 rad/s

time of motion, t = 10 s

The angular acceleration of the car is calculated as follows;

a_r = \frac{\omega_f - \omega_i }{t} \\\\a_r = \frac{25-10}{10} = 1.5 \ rad/s^2

Therefore, the angular acceleration of the car is 1.5 rad/s²

Calculate the amount of charge necessary to exert a force of 35 N in an electric field of 300 N/C.
densk [106]

Answer:

The amount of charge is "0.117 C" i.e., option A.

Explanation:

The given values are:

Force,

\vec{F} = 35 N

Electric field,

\vec{E} = 300 N/C

Charge,

q = ?

As we know,

⇒  \vec{F}=q\vec{E}

On substituting the given values in the above formula, we get

⇒  35=q\times 300

⇒   q=\frac{35}{300}

⇒   q=0.117 \ C

An engine performs 2700 J of work on a scooter. The scooter and rider have a combined mass of 150 kg. If the scooter started at
Finger [1]
Due to the principle of conservation of energy, the work done by the engine to move the scooter converts into kinetic energy of the scooter:
W=K= \frac{1}{2} M v^2
where M is the combined mass of scooter and rider, and v is the velocity of the scooter. Therefore, we can find the velocity as:
v=  \sqrt{ \frac{2W}{M} } =  \sqrt{ \frac{2\cdot 2700 J}{150 Kg} }=6 m/s
