What is general relativity​

Physics
1 answer:
Katena32 [7]3 years ago
7 0

Explanation:

General relativity is a theory of space and time. ... The central idea of general relativity is that space and time are two aspects of spacetime. Spacetime is curved when there is matter, energy, and momentum resulting in what we perceive as gravity. The links between these forces are shown in the Einstein field equations.

What is the closest distance the electrodes used in an NCV test can be placed on a nerve in order to measure the voltage change
sammy [17]

Answer:

0.1 m

Explanation:

The closest distance the electrodes used in an NCV test in oerder to measure

the voltage change as a response to the stimulus is 0.1 m.

This is because the shortest observable time period is not less than the action-potential time response of 1 mili second the length traveled by the sensation during this time is 1 m sec x 100 m / s =0.1 m, which is the shortest distance the electrodes could be positioned on the nerve.

If a 100N weight sits in an express elevator what will be the weight when the elevator is traveling at a constant speed
yarga [219]
This is a "trick" question.

If the elevator is traveling at constant speed, it means it is at rest. This means anything inside the elevator traveling at constant speed, weights the same as in an elevator not moving -also at rest-.

So the 100N weight's weight doesn't change in an elevator traveling at constant speed.

A proton moves through a magnetic field at 26.7 % 26.7% of the speed of light. At a location where the field has a magnitude of
iogann1982 [59]

Answer:

8.64283\times 10^{-14}\ N

Explanation:

q = Charge of proton = 1.6\times 10^{-19}\ C

v = Velocity of proton = 0.267\times c

c = Speed of light = 3\times 10^8\ m/s

B = Magnetic field = 0.00687 T

\theta = Angle = 101^{\circ}

Magnetic force is given by

F=qvBsin\theta\\\Rightarrow F=1.6\times 10^{-19}\times (0.267\times 3\times 10^8)\times 0.00687\times sin101\\\Rightarrow F=8.64283\times 10^{-14}\ N

The magnetic force acting on the proton is 8.64283\times 10^{-14}\ N
