C more than 1 second
Explanation:
it will take time since its 4.9 meters and how hard you throw it down
This question is a bit ambiguous because all parts of a scientific argument must be supported by valid data. However, among the choices, the closest synonym to "valid data" would be evidence. Evidence is the body of facts or information that support a given idea.
Microwaves are one of the lowest energies on the electromagnetic spectrum. While X-Rays are one of the highest energies on the electromagnetic spectrum. One similarity is that they are both on the electromagnetic spectrum. Also they both travel at the spped of light in a vacuum. One way they are different is They have different frequencies and wavelengths. Also they are used for different studies.
P = m v
250 = m5
250 = 5m
m = 50 Kg
Option C
Answer:
Explanation:
We shall apply Pascal's law here to find the solution .According to this law if we apply a pressure on a particular area over an in-compressible liquid it gets transferred to other point inside or over the surface of the liquid without getting diminished.
in the present case force is applied on a car to crush it which is enormous in magnitude. This force is 20000 N, which is also called output force Let the surface on which car is placed be A₂. We apply input force F₁ at other point over a small area be it A₁.
According to Pascal law ,
20000/ A₂ = F₁ / A₁
F₁ = 20000 X (A₁ / A₂)
= 20000 X 1/8
= 2500 N.
