Electromagnetism is the interaction between charged particles. It is very long ranged. It can manifest as a force causing like charges to repel and unlike charges to attract. ... The weak nuclear force is very short ranged and is not a force at all.
Answer:
Yes, since the choice of the zero o potential energy is arbitrary.
Explanation:
The kinetic energy is due to the motion of the object. The expression for the kinetic energy is as follows;
Here, m is the mass of the object and v is the velocity of the object.
The kinetic energy can not be negative as the velocity is squared. It can be zero and positive.
Potential energy: It is the energy is due to the position of the object.
The expression for the potential energy is as follows;
PE= mgh
Here, g is the acceleration due to gravity and height.
Height can be taken from the reference point, zero which can be taken below zero and above zero. Zero is taken as origin. Below zero, the height is taken as negative and above zero, the height is taken as positive.
The potential energy can be zero, positive and negative.
The total energy is the sum of kinetic energy and potential energy.
E= KE + PE
Here, KE is the kinetic energy and PE is the potential energy.
Therefore, the option (B) is correct.
<span>m^(- 5) = 1/35 → you know that: x^(- a) = 1/x^(+ a) = 1/x^a
1/m^5 = 1/35 → you take the inverse
m^5 = 35
[m^5]^(1/5) = 35^(1/5) → recall: (x^a)^b = x^(ab)
m^[5 * (1/5)] = 35^(1/5)
m^[1)] = 35^(1/5)
m = 35^(1/5)
The scientific notation is a number between 1 and 9 with few numbers after coma (point) completed by a power 10.
= [1.4 * 10^(3)] * [2.5 * 10^(- 6)] → you remove the brackets
= 1.4 * 10^(3) * 2.5 * 10^(- 6) → you order
= 1.4 * 2.5 * 10^(3) * 10^(- 6) → you make the multiplication
= 3.5 * 10^(3) * 10^(- 6) → recall: (x^a) * (x^b) = x^(a + b)
= 3.5 * 10^(3 - 6)
= 3.5 * 10^(- 3) ← answer C</span><span>
