The answer is 88m cause that’s the total distance the dog had ran in total and if that’s not the answer it’s 24m cause that’s how much further he had to go to retrieve it all the way back to the same position
Answer:
80 m tall
Explanation:
*** EDITED *** (I left out the '1/2' in the equation....D'Oh!)
It was descending 4 seconds ...because it landed 20 m away (at 5 m/s ...so 4 seconds)
displacement =<u> 1/2</u> a t^2
= 1/2 * 10 ( 4)^2 = 80 m tall
Answer:
a). Toward us faster than the second object.
Explanation:
According to the wave nature of light if the object is moving than its spectral lines will be shift.This shifting of spectral lines is known as Doppler effect.
if the two objects are moving towards each other it means that wave is compressed and the wavelength is shorter.Then the lines will be shift toward shorter wavelength if known as blue shift.
So the option a is correct.
a. toward us faster than the second object.
In order for a system to be in equilibrium , two conditions must be met. Net force must be 0.
Answer:
Volt
Explanation:
Voltage is what makes electric charges move. ... Voltage is also called, in certain circumstances, electromotive force (EMF). Voltage is an electrical potential difference, the difference in electric potential between two places. The unit for electrical potential difference, or voltage, is the volt.
The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt, applied to these points, produces in the conductor a current of one ampere, the conductor not being the seat of any electromotive force.
The coulomb (symbolized C) is the standard unit of electric charge in the International System of Units (SI). ... In terms of SI base units, the coulomb is the equivalent of one ampere-second. Conversely, an electric current of A represents 1 C of unit electric charge carriers flowing past a specific point in 1 s.
An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second.
