Answer:
Push or Pull Forces - example
When you push against a wall the force that you exert is an example of a push force. When you pull a trolley car the force that you exert is an example of pull force.
Power used by the clock=1.03 W
Explanation:
resistance= 14000 ohm
voltage=120 V
The formula for the power is given by
P=(120)²/14000
P=1.03 W
Answer:
Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity. It contains roughly 78% nitrogen and 21% oxygen 0.97% argon and carbon dioxide 0.04% trace amounts of other gases, and water vapor. This mixture of gases is commonly known as air. Explanation:
Answer:
-7.03645640575 Nm²/C
2.34548546858 Nm²/C
Explanation:
S = Surface area
Electric flux through the base is given by
The electric flux through the base is -7.03645640575 Nm²/C
Inside the tetrahedron there is no charge so total flux will be zero
The electric flux through the sides is 2.34548546858 Nm²/C
Answer:
1/4
Explanation:
The period of a simple pendulum is:
T = 2π √(L/g)
At half the period:
T/2
= π √(L/g)
= 2π √(L/(4g))
= 2π √((L/4)/g)
So the length would have to be shortened by a factor of 1/4.
