Work Done By Force with No Friction Determine the work that is being done by tension in pulling the box 50.0 cm along the table. Also determine the speed of the box after traveling the specified distance. 5.9 N 2.8 kg​

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Imagine you are riding on a yacht in the ocean and traveling at 20 mph. you then hit a golf ball at 100 mph from the deck of the yacht. you see the ball move away from you at 100mph, while a person standing on a near by beach would observe your golf ball traveling at 120 mph (20 mph + 100 mph). now imagine you are aboard the hermes spacecraft traveling at 0.1c (1/10 the speed of light) past mars and shine a laser from the front of the ship. you would see the light traveling at c (the speed of light) away from your ship. according to einstein’s special relativity, how fast will a person on mars observe the light to be traveling? a) 0.1c (1/10 the speed of light) b) c (the speed of light) c)1.1c (c+0.1c)

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
