Answer:
B
Explanation:
Let m be mass of the object and v be speed of object b.
Kinetic Energy of B = 1/2 mv^2
Kinetic Energy of A = 1/2 m(2v)^2
= 2 mv^2
= 4 (1/2 mv^2)
= 4 × Kinetic Energy of B
Hence Object A has four times the kinetic energy of object B (<em>A</em><em>n</em><em>s</em><em> </em><em>B</em><em>)</em>
Answer:
what was the answer
Explanation:
im taking the quiz and could use some help
The first thing that needs to be done is to find everything in the same units. 12 hours becomes 43200 seconds. Then find the distance traveled by light in that amount of time. Using the formula v=d/s, manipulate it so it looks like d=v*s. Then plug in the values: d=(3x10^8)*43200, d=1.3x10^13m. But you need to find this in kilometers. To do this, simply divide your answer by one thousand. Thus, a laser beam would travel 1.3x10^10 kilometers in 12 hours.
Step 1: Tell them to keep their eyes on the road.Step 2: Watch them to make sure they keep their eyes on the road.Step 3: Don't converse with them because you might risk distracting them.
It makes an awkward situation but it ensures that they'll feel so pressured to keep their eyes on the road or pull over so you can call a different ride.
Answer:
Longitudinal Mechanical Wave
Explanation:
Mechanical waves are the waves that require medium to propagate. And a longitudinal wave is a wave in which the vibration of the energy(here: mass specifically) is in the direction of propagation of wave.
Shock wave, strong pressure wave in any elastic medium such as air, water, or a solid substance, produced by supersonic aircraft, explosions, lightning, or other phenomena that create violent changes in pressure.
Shock waves travel faster than sound and their speed increases as the amplitude of the wave is increased but their intensity fades faster due to the fact that some of its energy gets expended in the form of heat due to the resistance of the medium.
