a cart is hanging from two strings the left spring scales read 2.5N. the left string makes an angle of 50 degrees. the right spring scale reads 3.6N the right string makes an angle of 50 degrees what is the mass of the cart

The earth exerts a gravitational force of 500 n on amy. what is amy’s mass in kg?

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.

1700 j of energy is lost from 0.14 kg object , the temperature decreases from 50°c to 45°c what is the specific heat of this object, amd what is the material ?
