Maintain their positions.
Solids are incompressible, just like liquids. The electrostatic forces between the atoms of block and the atoms of table prevent the two objects from moving into one another.
Answer:
d = 79 m
, d = -43 m
Explanation:
This in an exercise of movement in one dimension, the displacement is a vector and the distance is the scalar
Let's calculate the distance
d = 35 + 18 +26
d = 79 m
Displacement which is a vector
d = -35 +18 - 26
d = -43 m
thebold indicate vector. The negative sign indicates that the movement is to the left
The development of the microscope, a key innovation in the field of technology, lead to the development of Cell Theory, a key innovation in the field of science.
1. Answer:
The relationship between Force A and Force B is given as:
A = B
Explanation:
To produce acceleration to a body, an unbalanced force must be applied. Meaning that a Force must be applied to the body greater than that of Force of Friction.
In our case, a Force A is exerted on the crate which is moving with a constant velocity. As there is no acceleration, the force applied must be equal to the force of Friction B.
2. Answer:
The electron's acceleration is 1.756 x 10¹⁷ ms⁻².
Explanation:
Electric field exerts a Force on the electron given as:
F = 1.6 x 10⁻¹³ N
Rest mass of electron = 9.11 x 10⁻³¹ kg
According to newton's 2nd law of motion, a net force F applied on the electron must produce an acceleration 'a' which is directly proportional to the Force and inversely proportional to the rest mass of the electron given as:
a = F/m
a = (1.6 x 10⁻¹³)/(9.11 x 10⁻³¹)
a = 1.756 x 10¹⁷ ms⁻²
