How much torque do you exert if you push perpendicularly on a door with a force of 40 N at a distance of 70 cm from its hinges?
You set up an iron lightning rod. Its is 5.0 meters tall, with the top sharpened to a point and the bottom in good contact with the ground. You’ve determined that lightning bolts typically carry about 30,000 amps of current and last around 60 microseconds. a. How much charge is delivered by a typical lightning bolt? b. If you want the potential difference between the top and bottom of the lightning rod to be less than 120 V, what is...
For a vertical blade and motor setup, how much torque would be required to slice an average sized carrot?
How much force do you have to apply to hold a helium balloon of diameter 14 cm and density ρballoon = 0.1 kg/m^3 stationary under normal atmospheric conditions. Assume the density of air is ρair = 1 kg/m^3. Give a positive answer if you have to apply an upward force and a negative answer if you have to apply a downward force. Round your answer to 3 decimal places.

How much force must you and your friend each apply to the free
end of the door on the same side and perpendicular to the plane of
the door in order to produce the same torque as that produced by
both of you in part (a) above?
N
(d) What is the angular acceleration of the door?
rad/s2
A heavy swing door has a mass of m = 7,500 kg, a width W = 1.9 m, and a...
The lighthouse on Presque Isle is 21.0 m tall. You decide to verify this by attaching a pendulum mount to the top of the lighthouse and observing the pendulum as it swings. You use a rope that just barely misses the ground when it is hanging straight down. (a) If you attach a 2.0 kg mass to the end of the rope, pull it back, and release it, how long will it take for the pendulum to complete one cycle?...
A flywheel has a moment of inertia of 0.015 kg m?. a How much torque do you need to create an angular acceleration of 3 rad/s“ ? b With this torque, what would the angular speed be after 6 seconds? C What would the angular momentum be after 6 seconds? d What would the kinetic energy of rotation be after 6 seconds?
How much force do I have to apply to push a box with 8kg up the ramp with 15 degree incline with a acceleration of 2 m/s, coefficient is friction is 0.3,
can someone show me how to do every single procedure. thank
you so much !
3. Wanting to show your friends a cool demonstration that seems to break the laws of physics, you swing a pail of water in a vertical circle. You swing the bucket a couple times, no water comes out at the top, and complete each circle in 1.5 seconds. If your arm length is 60 cm and the bucket/water have a mass of 1.00 kg, determine...
You've decided to protect your house by placing a 6.8-m-tall
iron lightning rod next to the house. The top is sharpened to a
point and the bottom is in good contact with the ground. From your
research, you've learned that lightning bolts can carry up to 54 kA
of current and last up to 50 ?s.
Part A How much charge is delivered by a lightning bolt with these parameters? Express your answer to two significant figures and include the...
