4. Given that the specific heat of copper is 0.385J/g. K and if 81.21 of heat is applied to 17.8g of copper by how much will the temperature of the copper increase?

What is the magnitude of the resultant vector round your answer to the nearest tenth

Aperson standing in a canoe exerts a force of 700 n to throw an anchor over the side. find the acceleration of the canoe if the total mass of the canoe and the person is 100 kg?

Point charges q1 = 51 µc and q2 = −27 µc are placed 1.0 m apart, with q2 on the right. what is the force (in n) on a third charge q3 = 19 µc placed midway between q1 and q2? (assume the positive direction is to the right. indicate the direction with the sign of your answer.)
