Answer:
Alternating current will produced by a wire breaking magnetic field lines and changing the polarity.
Explanation:
Answer:
v₀ = 26.17 m/s
Explanation:
If
R = Xmax = 50 yards = (50 yards)*(0.9144 m / 1 yard) = 45.72 m
t = 5 s (Time of Flight)
we can apply the equation:
R = V₀x*t ⇒ V₀x = R / t = 45.72 m / 5 s ⇒ V₀x = 9.144 m/s
then we use the equation of Time of Flight:
t = 2*V₀y / g ⇒ V₀y = g*t / 2 = (9.81 m/s²)*(5 s) / 2 ⇒ V₀y = 24.525 m/s
Finally we apply
v₀ = √(V₀x² + V₀y²) ⇒ v₀ = √(9.144² + 24.525²) m/s
⇒ v₀ = 26.17 m/s
Mass of solid cube = 725g = 0.725kg Length of each side = 6.35cm =0.0635 m As volume = length ×length×length Volume= 0.0635×0.0635×0.0635 =0.1905 m³ ρ = m/V ρ= 0.725/0.1905 = 0.138 kg/m³ Answer
Since this is a right-angled triangle,
Use tan 30 to find BC
Use tan 75 to find AC
Then subtract both answers to find AB
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
