Which of the following objects uses two converging lenses to produce two images, the second of which is virtual, magnified, and inverted Camera

Compound microscope

Corrective eyeglasses

Slide projector

A) A block of mass, m, is pushed up against a spring, compressing it a distance x, and is then released. The spring projects the block along a frictionless horizontal surface, giving the block a speed v. The same spring projects a second block of mass 4m, giving it a speed 3v. What distance was the spring compressed in the second case?B) Initially a body moves in one direction and has kinetic energy K. Then it moves in the opposite direction with three times its initial speed. What is the kinetic energy now?

A car travels at a steady speed of 10 m/s. What distance is covered in a minute?

if a train travelling at 10m/s starts to accelerate at 1m/s^2 for 15s on a straight track, calculate its final speed in m/s

Answers

Answer:

-5 m/s

Explanation:

vo = 10 m/s

a = -1 m/s²

t = 15 s

v = vo + at

= 10 + (-1)(15)

= -5 m/s

(actually the train has come to a stop at t = 10s)

Answers

Answer:

{ \tt{(1.54 * {10}^(6)) + (6.15 * {10}^(6)) }} \n = { \tt{(1.54 + 6.15) * {10}^(6) }} \n = { \tt{7.69 * {10}^(6) }}

Please can some one explaine fore me What is work done

Answers

In Physics, 'work' has a very clear definition:

It's (strength of a force) times (distance through which the force acts).

'Work' has the units of Energy.

If you push against a shopping cart with 30 newtons of force, and
you keep pushing while the cart moves 4 meters, then you have
done (30 x 4) = 120 newton-meters of work = 120 "Joules".

A current of 4A flows in a wire of resistance 60 ohm. calculate electrical energy consumed in 2 min.

Answers

Power dissipated = energy/second= (current)² x (resistance)

Power dissipated = energy / second = (4)² x (60) = 960 joules per second= 960 watts

Energy = (power) x (time) = (960 watts) x (2 minutes) x (60 sec/minute)

                 = 115,200 joules

Typically, water runs through the baseboard copper tubing and, therefore, fresh hot water is constantly running through the piping. However, consider a pipe where water was allowed to sit in the pipe. The hot water cools as it sits in the pipe. What is the temprature change, (ΔT), of the water if 193.0 g of water sat in the copper pipe from part A, releasing 2665 J of energy to the pipe? The specific heat of water is 4.184 (J/g)⋅∘C.
