Answer:
The answer is "Option A".
Explanation:
In the given scenario, Two metal plates were produced in contrast to values separated by a small distance and three potential points for just a slight net charge are accessible. All three points would have the same electrical energy since the power generation is consistent from both sides as well as the position is placed at a slight net value so it has the highest electrical energy.
Explanation:
There are generally two types of collisions between objects - elastic and inelastic.
Elastic collisions are those that converse kinetic energy. Inelastic are those that do not conserve kinetic energy.
In the ideal inelastic collision and elastic collisions, momentum is conserved.
Typically, ideal inelastic collisions are represented when both masses stick together after the collision.
The problem statement gives no indication that this is an ideal inelastic collision (the cars stick together) or an inelastic collision (no energy degradation expression is given). Therefore, we should assume that the cars are experiencing an elastic collision.
Since both momentum and kinetic energy are converved, we can observe that...
where v is the initial velocity and u is the final velocity (after the collision)
The problem statement gives us three of the four unknowns. So we can easily apply either equation to solve the the velocity of the 1600-kg car after the collision. Momentum is easier to work with.
Answer:
The total distance is equal to the change in total position of the person, but the displacement of the person is zero.
Explanation:
- The distance is the total change in the positions of the toy robot. it is having only magnitude and it is a scalar quantity.
- The displacement is the difference between the final and initial position of the toy robot. it is a vector quantity having magnitude and direction
- Since the distance is the change in positions, so the magnitude of the distance will be equal to the up and down distance covered.
- If the toy robot travels in a straight line path and returns back to its original location, the magnitude of the distance and displacement doesn't depend on the speed of the toy robot.
Answer:
Electric Potential V=130 V
Explanation:
Electrical potential inside a hollow sphere is constant and is equal to electric potential of surface
So
Electric Potential V=130 V
Answer:
The order =
Explanation:
To miss the crack at a given distance is apparently not the same as the uncertainty that occurred in the distance while falling from the tower. However, it is believed that the uncertainties in both cases appear to be the same.
So, let's work it out together
According to Heisenberg's uncertainty principle:
Also; if we recall from the equation of motion that:
So, if u = 0 and a = g
Then;
From (2)
Making (s) the subject, we have:
By differentiation;
where;
from uncertainty principle
This implies that:
here;
v = 2gH
So;
Thus, the order =
