Answer: a= 2 m/s²
Explanation: acceleration = change of speed/ time = 20 m/s / 10 s
The mass of the van will be 2.5 kg, Mass is found as the ratio of the force and the acceleration.
<h3>What is force?</h3>
Force is defined as the push or pull applied to the body. Sometimes it is used to change the shape, size, and direction of the body.
Force is defined as the product of mass and acceleration. Its unit is Newton.
F=ma
5.5 kN = m × 2.2m/s²
m= 2.5 kg
Hence,the mass of the van will be 2.5 kg,

D) Gamma Rays
Explanation:
Gamma rays can transmit through matter.
Answer:
Explanation:
The capacitor of a parallel-plate capacitor is given by:
where
A is the area of each plate
d is the separation between the plates
is the vacuum permittivity
The energy stored in a capacitor instead is given by
where
Q is the charge stored in each plate
Substituting the expression we found for C inside the last formula,
And re-arranging it
Now if we substitute
We find the charge stored on the capacitor:
I believe that the answer is <span>C. The atmosphere scatters blue light more than yellow light.</span>
