Light travels at 3.0 * 108 m/s in a vacuum. Use the index of refraction for water to determine the speed of light in water. Round your answer to the nearest tenth.

A car advertisement claims their car can go from a stopped position to moving 60 miles per hour in 5 seconds. The advertisement is describing the car's

A train moves forward at a constant speed. What is true about the forces acting on the train? SC. C. 2.3.6 A. The forward forces are equal to the forces acting in the backward direction. B.

What is the Celsius eguivalent of 212°F? 32°C 0°C 100°C 212°C

Which statement describes a force between charged particles? 1) Like charges repel each other. 2) Like charges attract each other. 3) Unlike charges repel each other

A sample of ice at 0°C has a mass of 23 g and a volume of 25 cm^3. Why does ice float on water? The density of water is 1 g.

Try this out. Use a calculator! We can use the formula KE=0.5m*V^2. To find the kinetic energy (KE) of a payload of mass (m) 100 kg as it flies through the air at the velocity (v) of 55 m/s. (Multiply 0.5 x the mass x velocity squared.

Which group of measurements is the most precise? A) 2 g, 3 g, 4 g B) 2 g, 2.5 g, 3 g C) 2.0 g, 3.0 g, 4.0 g, 5.0 g D) 2.0 g, 3.0 g, 4.0 g

A 946.4 kg (2083 lb) car is moving at 14.8 m / s (33.0 mph). Calculate the magnitude of its momentum.

How do the positions of the hot and cold water affect the speed of convection

A fan is to accelerate quiescent air to a velocity of 12.5 m/s at a rate of 9 m3/s. Determine the minimum power that must be supplied to the fan. Take the density of air to be 1.18 kg/m3.
