The planet uranus is tilted nearly on its side so that its axis or rotation is only 8 degress abway from its orbit plane. if you lived at latitude 45 degrees on uranus for what fraction of the uranian year would answer?

A man is sitting on a 20 m height building and his mass is 50 kg. Calculate the mechanical energy.

What is the slope of a line that is perpendicular to a line whose equation is - 2y=3x+7 Enter your answer in the box.

The specific heat of a 101 g block of material is to be determined. The block is placed in a 25 g copper calorimeter that also holds 60 g of water. The system is initially at 20°C. Then 125 mL of water at 80°C are added to the calorimeter vessel.

How do I calculate initial speed by using the slope of a graph? The graph shows the relationship between S { (sin2ϴ) / g} and the average range of a projectile in meters.

You push a 50 kg wooden box across a wooden floor at a constant speed of 1.0 m/s. The coefficient of kinetic friction is 0.15. Now you double the force on the box. How long would it take for the velocity of the crate to double to 2.0 m/s?

A star is in hydrostatic equilibrium when the outward push of pressure due to core burning is exactly in balance with the inward pull of gravity.

How are mass and weight different? a. Mass is the space an object takes up and weight is the effect of gravity on mass. b. Mass is the amount of matter and weight is the effect of gravity on mass. c.
