Mass of the sun = 1.99x10^30 kg. Energy released by 1 megaton bomb is about 4x10 ^15 joules.

Please show me how to solve using vav=d/t.

Please show me how to solve using vav = d/t.

the 2 kg block in the figure slides down a frictionless curved ramp, starting from rest at a height of h=2.0 m the block the slides d= 8.0 m on a rough horizontal surface before coming to rest. what...

A stationary shell explodes into 3 pieces. 3kg piece travels north. two other fragments travel opposite directions of south west 25 degrees and south east 25 degrees. What is the speed of each of...

What volume of NaOH is needed to make 50mL of a 1M solution?

Why are the changes in election affinity as one goes down a group in the periodic table not nearly as large as variations in ionization energy. My book does not explain this concept...

Diagonal relationships in the periodic table exist as well as the vertical relationships. For example, Be and Al are similar in some of their properties as are B and Si. Rationalize why these...

If a circuit with a 9 Ohms of resistance is powered by a 1.5 Volt battery, what would happen to the voltage drop across the resistor if a second 1.5 Volt battery was connected in series with...

How many orbitals can have the designation 5p, 3dz^2, 4d, n=5, n=4?

The legs of a tripod make equal angles of 90° with each other at the apex, where they join together. A 111-kg block hangs from the apex. What is the compressional force in each of the three legs?...

SSF=ratio of track/(2•height of center of gravity). Do I just start taking guesses and use ac=v2/R. Then use a=g•SSF, to get a comparative answer? For example: 50mph--- ac=502/50=50. SSF=50/32...

revolutions before coming to rest. What is the tangential acceleration of a point on the disk 5.00 cm from the axis?

of a centrifuge in which a particle 10.0 cm from the axis of rotation experiences a radical acceleration of 1.00 x 10^3 times gravitational acceleration g.

a. Find the angular velocity of disk. b. Find the speed of a point on the disk 6.00 cm from the axis of rotation.

A car starting from rest accelerates to the left. It takes 14 seconds to travel a distance of 20 meters. What is the car's average velocity? I'm really confused by this question I'm not sure...

Consider an electron for a hydrogen atom in an excited state. The maximum wavelength of electromagnetic radiation that can completely remove (ionize) the electron from the H atom is 1460 nm. What...

swinging down, it undergoes and elastic collision with sphere 2 whose mass is 75 g. a) What is the velocity of the sphere 1 just after the collision? b) To what height does the sphere 1 swing...

With what speed will the ball leave the barrel once the gun is fired? The spring constant is 7.5 N/cm. Assume no friction and a horizontal gun barrel.
