Answer: 18 blocks in total ( 17 add to the original in contact with the ground)
Explanation:
The pressure on the face in contact with the ground ( we choose the face 0.15m x 0.082m)
Pressure= Force ( weigth) /Area
1 Atm = 101325 Pascal [N/ m^2]
Answer:
The acceleration of a 1000 kg car subject to a 550 N net force = 0.55 m/s^2
Explanation:
Given:
F = 550 N
m = 1000 kg
To Find:
a = ?
Solution:
So by the equation by Newton's 2nd Law of Motion,
F = m x a
550 N = 1000 kg x a
a = 550 N/ 1000 kg
a = 0.55 m/s^2
Therefore,
The acceleration of a 1000 kg car subject to a 550 N net force = 0.55 m/s^2

The frequency of the light source is 1.5 x 10¹⁵ Hz.
<h3>
Frequency of the light source</h3>
The frequency of the light source is determined using the following equations;
c = fλ
where;
c is speed of light
f is the frequency
λ is the wavelength
f = (3 x 10⁸) / (2 x 10⁻⁷)
f = 1.5 x 10¹⁵ Hz
Thus, the frequency of the light source is 1.5 x 10¹⁵ Hz.
