Given: Weight W = 100 lbs convert to Kg = 45.36 Kg
Height h = 8 Ft convert to meter = 2.44 m
Time t =10 s
Required: Power output
Formula: P = W/t Work = Force x distance or Work = mgh
P = mgh/t
P = (45.36 Kg)(9.8 m/s²)(2.44 m)/10 s
P = 108.46 J/s
P = 0.15 Horsepower
Xrayssssss because they are the closest to gamma rays, and they have the highest frequency
All transverse waves can be polarized. this is because these waves oscillate at 90 degrees to the direction of energy movement.
Answer:
Option B: change the objective lens
Explanation:
The revolving nosepiece is one of the parts of a microscope. Its responsibility is to hold the objective lenses.
Answer: 8 years
Explanation:
According to Kepler’s Third Law of Planetary motion <em>“The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”:</em>
<em />
(1)
In other words: this law states a relation between the orbital period of a body (moon, planet, satellite, comet, asteroid) orbiting a greater body in space (the Sun, for example) with the size of its orbit.
However, if is measured in years (Earth years), and is measured in astronomical units (equivalent to the distance between the Sun and the Earth: ), equation (1) becomes:
(2)
This means that now both sides of the equation are equal.
Knowing and isolating from (2):
(3)
(4)
Finally:
This is the period of the asteroid
