<em>The options are not well presented; However, the questions can still be solved</em>
Given
Required
Determine the final displacement
This question will be answered using the following equation of motion
Where s represent the total distance
s is the distance between the initial and final displacements and is calculated as thus;
Where x represents the final displacement
Substitute for ---- The initial velocity
Substitute for s
<em>Hence, the above equation can be used to determine the final displacement by solving for x</em>
Answer:
r = 0.11 m
Explanation:
Let's suppose that the magnetic field is perpendicular to the vector speed. In that case, the centripetal force would be the same as the Lorentz force.
.
Solving this equation for r, we will have:
Now, to find r we need to get the speed of the particle. Let's use the law of conservation of energy. The kinetic energy is equal to the electric potential energy:
, but
So we would have:
, then
Finally
Have a nice day!
Answer:
C
Explanation:
The temperature of an object does not change when it is going through a phase change, since there is a single specific point on the temperature gradient where that change occurs. Once the phase change has occurred, the water's temperature can continue to change in that direction, but during the phase change it does not. Hope this helps!
Answer:
r = 9521.29
Explanation:
Given:
Gravitational Force = (Fg)
Student Mass 1 = 71 kg (M)
Student Mass 2 = 67kg (m)
Gravitational constant = (G)
r = 9521.29
Many plutons clump together as they grow through the crust.
