Two vectors A→ and B→ have magnitude A = 2.90 and B = 3.02. Their vector product is A×B = -4.96k^ + 2.04 i^. What is the angle between A and B?

the blocks on the horizontal table

are in contact with one another. The first block is connected to a massless

string that passes over a massless and frictionless pulley and then is fastened to

a hanging object of mass M.

a) Assuming the surface of the table as frictionless

i) determine the acceleration of the system.

ii) find the tension in the string.

iii) find the interaction forces between M1 & M2.

Differentiate between the function of the thread, glass rod and stirrer used during the determination of specific heat capacity of a solid by method of mixture

A long Straight wire carries 5A along a positive x axis and a second wire carries 7A along positive y axis find their combine field at the point x=4cm and Y=6cm

. A football coach walks 18 meters westward, then 12 meters eastward, then 28 meters westward, and finally 14 meters eastward. For this motion, a. What is the distance traveled? b. What is the displacement? c. What is the coach's speed? d. What is the coach's velocity?

A particle p is let fall vertically from a height to the ground. Another particle Qjs projected vertically down three seconds later with a velocity of 50 meter per seconds from the same height. If both particles reached the ground simultaneously,calculate the time each particle reach the ground and the distance traveled by each particle
