Answer:

Construction pulleys are used in order to lift and place heavy materials. Curtains at a theatre are moved using pulley systems that pull the curtains apart. Blinds on windows operate using a pulley system to move the blinds up and down.

g When the movable mirror of the Michelson interferometer is moved a small distance X while making a measurement, 246 fringes ar
zhenek [66]

Answer:

X = 69.1 x 10⁻⁶ m = 69.1 μm

Explanation:

The relationship between the motion of the moveable mirror and the fringe count of the Michelson's Interferometer is given by the following formula:

d = mλ/2

where,

d = distance moved by the mirror = X = ?

m = No. of Fringes counted = 246

λ = wavelength of light entering interferometer = 562 nm = 5.62 x 10⁻⁷ m

Therefore,

X = (246)(5.62 x 10⁻⁷ m)/2

Therefore,

<u>X = 69.1 x 10⁻⁶ m = 69.1 μm</u>

A person takes a trip, driving with a constant
podryga [215]
For this problem, we are asked to calculate for the distance traveled. We set up the equations as follows:
Distance = 61 km/hr * (time + 20.8/60 s) Distance = 98.5 km/hr * time

We equate the two equations, then we can solve for the time spent on the trip. Hope this answers the question. Have a nice day.

A body is thrown vertically upwards.Its velocity keeps on decreasing. What happens to its kinetic energy when it reaches the max
Nikolay [14]
The kinetic energy will rise once the body comes back down. As it goes up, the potential energy increases while the kinetic energy decreases. Once the body is at its maximum height, the potential energy is at it’s highest. When it starts falling, it will gain kinetic energy and lose potential energy.

The more _________ an electron has, the further away it can be from the nucleus. mass
Monica [59]

Answer:

ectron's further from the nucleus are held more weakly by the nucleus, and thus can be removed by spending less energy. Hence we say they have higher energy. The Coulomb interaction energy between a nucleus of atomic number and an ele
