Answer:
20N
Explanation:
Ratio of N to cm-
10:2
so to make 2=4 times 2 so The ratio is now-
20:4
so to move 4 cm you need to push 20N.
Answer:
100/10 = 10 , 10 × 10 = 100÷20 = 5
I'm pretty sure its wrong
Answer: The horizontal location of the plane will BE OVER THE BOMB
Explanation:
As soon as the bomb was dropped, the bomb will fall under gravity (free fall) and the location of the plane continues to increase horizontally till the bomb reaches the ground which is a falling distance to be travelled by the bomb at 9.8m/s²
Mainly because of the higher energy of blue light than red light.
In fact, light is made of photons, each one carrying an energy equal to
![E=hf](https://tex.z-dn.net/?f=E%3Dhf)
where h is the Planck constant while f is the frequency of the light.
The frequency of red light is approximately 450 THz, while the frequency of blue light is about 650 Hz. Higher frequency means higher energy, so blue light is more energetic than red light and therefore it can cause more damages than red light.
Answer:
The Normal and Gravitational Force
Explanation:
The normal force pushes up and is between the ground and the scale. The gravitational force is the force exerted on the ground.
