What else can I help you with?
An adult pulls a child 350-meters across the snow on a sled. They exert a force of 25 newtons at an angle of 30.0 Deg above the horizontal to pull the rope attached to the sled. What is the force?
The horizontal component of the force is given by 25 * cos(30°), which is approximately 21.65 N. This is the force that is responsible for pulling the sled across the snow.
What happens if the air does not exert pressure?
If air did not exert pressure, objects would not experience resistance or buoyancy as they move through it. This would result in a lack of stability and support for structures, making it difficult for living organisms to survive. Additionally, weather patterns would be drastically altered, as air pressure plays a key role in the distribution of heat and moisture across the planet.
What are the things that can or cannot exert force?
Things that can exert force include objects with mass, living organisms, and physical phenomena like gravity and electromagnetism. Things that cannot exert force include abstract concepts, such as ideas or emotions, and non-physical entities like light or sound.
Will you exert more pressure when you stand on your toes or when you stand flatfooted?
You will exert more pressure when you stand on your toes because your body weight is concentrated on a smaller surface area. This increases the pressure on the toes compared to when you are standing flatfooted with the weight distributed across a larger surface area.
Two examples of objects on which you exert forces when you are doing your schoolwork?
downward force of your body on the chair force on pen to write with
D'Andre expends 120 W of power in moving a couch 15 meters in 5 seconds How much force does he exert?
40 N
You expend 1000 W of power in moving a piano 10 meters in 5 seconds How much force do you exert?
1,000 N apex=500 N
Felix expends 100 W of power to climb 10 meters in 20 seconds How much force does he exert?
his force is clearly 200N
What if your exert 800 N of force in moving a piano 10 meters in 5 seconds how much power do you expend?
Work = (800 newtons) x (10 meters) = 8,000 newton-meters = 8,000 joulesPower = (work) / (time) = (8,000) / (5) = 1,600 watts
How much force did the puck exert on the hockey stick at 0.200kg in a 6ms in 2 seconds?
Not that much actually.
Calculate the power in watts used if you exert 50 joules of work in 5 seconds?
Watts is joules per second, so 50 joules in 5 seconds is 10 watts.
How are productive resources among people and businesses in the US?
they exert the probability of mankind and its ways of living

Find the work you do when you exert a force of 40 N to run a distance of 18 m in 4 seconds?
The work is Work= FD= 40x18= 720 Joules. The power is W/seconds = 720/4= 180 Watts.
D Andre expends 120 W of power in moving a couch 15 meters in 5 seconds how much force does he exert?
Power=120W=work/time=Force*distance/time. so' 120=F*15/5, or 120*5=F*15 , so, F=600/15=40N
What molecules exert primary control over basic life processes of all living processes of all living things forming a chemical link between the generations?
