What equals 5 cm in meters
A man and a woman exert a total of 900 N by pushing a car 20 meters across the street The man exerts twice as much force as the woman How much work does the man do
The man exerts a force of 600 N and the woman exerts a force of 300 N. Work done by the man = Force x displacement = 600 x 20 = 12,000 J Hence, the man performs 12,000 joules of work.
How long will it take a driver to drive 300 miles by maintaining a constant speed of 60 miles per hour
Time = Distance/Speed = 300 miles/60 mph = 5 hours
The tangent of an angle equals the ratio of the
Sine of the angle to its cosine.
How much work is done when a 6.0 n weight is raised 2.0 meters off the ground
A force of 20 N gives a ball an acceleration of 4.0 ms on a level frictionless surface what is the mass of the ball
Which of these formulas is correctly rewritten from the original formula to solve for b
b = 1/2 (a - c)
or for a = 3b - 2c: b = 1/3 (a + 2c)
for a= 2bc + d is b= (a-d)/2c
a= 2b +c is c= a - 2b
b=1/3(a-2c)
In the metric system the prefix for ½Â½Á½ÁÎÁ½ÁÁ½Á½Á is
A pulley system is used to lift a 2000 newton engine up a distance of 3 meters The operator must apply a force of 250 newtons to the chain of the pulley system to lift the motor To lift the engine fi
You drive a car 2 hours at 40 miles per hour 2 hours at 60 miles per hour how many miles will you travel
If you drive a car at 40 miles per hour for two hours,then the
distance covered will be 80 miles.If you drive the car for another
2 hours at 60 miles per hour ,then you will cover another 120
miles.The total distance you will cover is thus 80 miles + 120
miles = 200 miles.
Which of these formulas is correctly rewritten from the original formula to solve for d a equals 2bc plus d
