The correct answer to the question is D) 6 joules.

EXPLANATION:

As per the question, four measurements are given i.e 24 m/s, 60 mg, 15 L and 6 J.

We are asked to determine the measurement which corresponds to energy.

Energy is measured in various units like joule, erg, electron volt etc.

Joule is the unit of energy in S.I system.

Hence, the correct measurement which corresponds to energy is 6 joules.

All other measurements like 24 m/s, 60 mg and 15 L are not the measurements of energy. These are the measurements of speed, mass and volume respectively.

Answer:

$a_c=1.57\frac{m}{s^2}$

Explanation:

In order to find its centripetal acceleration we need to use the next equation:

$a_c=\frac{v^2}{r}$

So, we need to find its velocity in first place. Considering that the time T required for one complete revolution is called the period. For constant speed is given by:

$T=\frac{2\pi r}{v}$

Solving for v, considering that in this case T=1.3min=78s, and r=242

$v=\frac{2\pi *(242)}{78} =19.49398518m/s$

Finally, replacing v in the centripetal acceleration equation:

$a_c=\frac{(19.49398518)^{2} }{242}=1.570311811m/s^2$

A 0.56 kg model rocket produces 53 newtons of upward thrust as it shoots upward off the launch pad. With what acceleration meter

Yanka [14]

resultant force = thrust – weight

acceleration = resultant force (newtons, N) divided by mass (kilograms, kg).

Acceleration = resultant force divided by mass

53N/0.56

=94.64 approximately 95

= 95m/s^2

This means that, every second, the speed of the rocket increases by 95m/s2

the S.I unit of Acceleration is meter per second square.
