Answer:
The railroad is 20,63 m height.
Explanation:
In this problem we have two objects that encounter on a given time that is the same for both objects.
Objects are:
The car moves in constant velocity of 19 m/s. The car makes a trajectory of 39 mts before encounter the bolt that hits the windshield.
Then, for the car we need to find the time that takes to make the trajectory, and we use the formula for uniform rectilinear motion (URM):
where v is velocity, s is space or trajectory, and t is time.
The time t=2.052 sec is the time that takes the bolt to fall and hit the windshield, so, we have to take this time and replace it in following formula that applies for <em>free fall objects:</em>
The distance between two nodes is HALF the wavelength. So if the wavelength is 2cm the distance between two adjacent nodes is 1 cm. does this help?
Answer:
zero
Explanation:
For a solid conducting sphere, charges are present on the surface of the sphere due to a phenomenon known as electrostatic sheilding. This affects the charge present in the body and makes it zero. However, the electrostatic potential appears to be equal to the whole present point that shows on the surface. The surface of a spherical conducting solid sphere is known as an equipotential surface. Thus, the potential difference between the two opposite points on the surface of the sphere will also be zero.
