If an engine can produce 670 J of energy in 1 min, how many watts can it output?
daser333 [38]

Answer:

11.2Watts

Explanation:

Given parameters:

Energy produced by the engine  = 670J

Time taken  = 1min  = 60s

Unknown:

Number of watts it can output  = ?

Solution:

This problem entails finding the power of the engine.

Power is the rate at which work is being done.

So;

      Power  = \frac{Work done }{time}  

       Power  = \frac{670}{60}    = 11.2Watts

The fire alarm goes off, and a 75 kg firefighter slides down a pole with a constant acceleration of a = 6 m/s square. What is th
Alex17521 [72]

Answer:

450N

Explanation:

Given data

Mass m= 75kg

Acceleration= 6m/s^2

From the Newtons first law, F=ma

substitute

F=75*6

F= 450N

Hence the force is 450N

Which fundamental force causes some forms of radioactivity? A. Gravity B. Electromagnetic force C. Strong nuclear force D. Weak
I am Lyosha [343]

Hello.

The answer is: D. weak nuclear force.

The weak force causes beta decay, a form of radioactivity. It could not be explained by the strong nuclear force, the force that’s responsible for holding the atomic nucleus together, because this force doesn’t affect electrons.

It couldn’t be the electromagnetic force, because this does not affect neutrons, and the force of gravity is far too weak to be responsible.

Have a nice day
