The answer is A. The outer lines change as it moves
Answer:
a = 1 m/s² and
Explanation:
The first two parts can be seen in attachment
We use Newton's second law on each axis
Y axis
Ty - W = 0
Ty = w
X axis
Tx = m a
With trigonometry we find the components of tension
Sin θ = Ty / T
Ty = T sin θ
Cos θ = Tx / T
Tx = T cos θ
We calculate the acceleration with kinematics
Vf = Vo + a t
a = (Vf -Vo) / t
a = (20 -10) / 10
a = 1 m/s²
We substitute in Newton's equations
T Sin θ = mg
T cos θ = ma
We divide the two equations
Tan θ = g / a
θ = tan⁻¹ (g / a)
θ = tan⁻¹ (9.8 / 1)
θ = 84º
We see that in the expression of the angle the mass does not appear therefore you should not change the angle
The electrons in the positive object are attracted to the negatively charged object. Some of the electrons move from the positive object to the negative object.
an example of this is lightning because the positive electrons on/in the earth are attracted to the negative electrons in the clouds and sky so the positive move to the negative charge.
Strong nuclear force is most like electrical force because they are both related to distance statement best describes the similarities between fundamental forces.
<u>Option: D</u>
<u>Explanation:</u>
There are four forms of fundamental forces in nature. They are called gravitational force, electromagnetic force, strong nuclear force, and weak nuclear force. Strong nuclear force is a spin-dependent, charging-independent force that arises into being due to the mutual association of gluons binding protons and neutrons.
It is also hundred times more powerful than electromagnetic force. Poor nuclear capability comes into being during radio-active decay. This force is due to the interaction of 'w' and 'z' bosons (particles such as protons and neutrons with integral or zero spin) that are heavier in nature. The function of this force is to turn protons into neutrons and vice versa.
