Answer:
The detailed explanations is attached below
Explanation:
What is applied is the De brogile equation and the equation showing a relationship between Energy, speed of light and wavelength.
The explanation is as attached below.
The mass of the first block will be three times the mass of the second block.
According to Newton's second law of motion, the force acting on a body is directly proportional to the acceleration as shown;
F is the acting force
m is the mass
a is the acceleration of the body
Given the following parameters
Constant force F = 1N
For the first block with the acceleration of "a"
1 = m₁a
a = m₁/1
m₁ = a .................1
For the second block, acceleration is thrice that of the first. This means;
F = m(3a)
1 = 3ma
..........................2
Divide both equations
From the calculation, we can conclude that the mass of the first block will be three times the mass of the second block.

Length* width*height =volume always
Answer:
a = -3.9m/s²
Explanation:
Given the following data;
Initial velocity = 66m/s
Displacement = 560m
To find the acceleration, we would use the third equation of motion
V² = U² + 2aS
Substituting into the equation we have
0² = 66² + 2*a*560
0 = 4356 + 1120a
-1120a = 4356
a = - 4356/1120
a = -3.9m/s²
The Answer is B
