Kinetic energy....

Physics
1 answer:
Solnce55 [7]3 years ago
7 0

Explanation:

Given parameters:

mass of bullet 1 = 0.0014kg

velocity of bullet 1 = 396m/s

mass of bullet 2 = 7.1 x 10⁷kg

velocity of bullet 2 = 13m/s

Unknown;

Comparing the kinetic energy

Solution:

Kinetic energy is the energy due to the motion of a body.

   K.E = \frac{1}{2} m v^{2}

bullet 1:

  K.E =  \frac{1}{2} x 0.0014 x  396^{2} = 109.8J

bullet 2:

 K.E =  \frac{1}{2} 7.1 x 10⁷ x  13^{2} = 6 x 10⁹J

The second bullet has more kinetic energy than the first one.

Transverse waves are sent along a 4.50 m long string with a speed of 85.00 m/s. The string is under a tension of 20.00 N. What i
frutty [35]

Answer:

m = 0.0125 kg

Explanation:

Let us apply the formula for the speed of a wave on a string that is under tension:

v = \sqrt{\frac{F}{\mu} }

where F = tension force

μ = mass per unit length

Mass per unit length is given as:

μ  = m / l

where m = mass of the string

l = length of the string

This implies that:

v = \sqrt{\frac{F}{m/l} }\\ \\v = \sqrt{\frac{F * l}{m} }

Let us make mass, m, the subject of the formula:

v^2 = \frac{F * l}{m}\\\\m = \frac{F * l}{v^2}

From the question:

F = 20 N

l = 4.50 m

v = 85 m/s

Therefore:

m = \frac{20 * 4.5}{85^2}\\\\m = \frac{90}{7225}\\ \\m = 0.0125 kg

An astronaut is a short distance away from her space station without a tether rope. She has a large wrench. What should she do w
Hitman42 [59]

Answer: b. Throw it directly away from the space station.

Explanation:

According to <u>Newton's third law of motion</u>, <em>when two bodies interact between them, appear equal forces and opposite senses in each of them.</em>  

To understand it better:  

Each time a body or object exerts a force on a second body or object, it (the second body) will exert a force of equal magnitude but in the opposite direction on the first.  

So, if the astronaut throws the wrench away from the space station (in the opposite direction of the space station), according to Newton's third law, she will be automatically moving towards the station and be safe.
