Which tools collect images during space exploration? Check all that apply. rovers orbiters satellites space shuttles space stati
grigory [225]

Answer:

1. Rovers- These are vehicles which are designed to move on the surface on any celestial body and collect samples, data and images. Sometimes, these can be used to transport mission crew members.

2. Orbiters- These are spacecrafts designed to orbit any celestial body and collect data in form of images.

3. satellites- artificial satellites are placed in the orbit of celestial bodies for various purposes. There are various types of satellites like communication satellite, weather satellites, space telescopes. These collect images and data inform of signals.

4. space stations: It is a satellite where research and experiments take place. Images are also collected for research purpose.

Space shuttle is a wrong option because it is just a vehicle to transport these satellites and probes into the space and place in the orbit or surface of celestial body.

A small pebble and one large boulder start at the same height and begin rolling down the side of a mountain. Which object would
vitfil [10]

Answer:

The small pebble

Explanation:

Since the potential energy, P.E lost equals kinetic energy, K.E gained,

P.E = K.E

P.E = mgh = K.E

So, K.E = mgh where g = acceleration due to gravity and h = height of drop

Since h and g are constant

K.E ∝ m

So, the kinetic energy of the object is directly proportional to its mass. Thus, the object with the smaller mass has the lesser kinetic energy.

Since the object with the smaller mass is the small pebble, so the small pebble would have less kinetic energy as it crashes on the road at the bottom of the mountain.

How fast will a car at rest be going if it accelerate at 8m/s/s for 3s
aleksandr82 [10.1K]

Answer:The car will be going 24 m/s.

Explanation:The car will be going 24m/s because it will have accelerated at 8m/s for 3 seconds and because acceleration is equal to change in velocity over time, the car's velocity will have increased by 24m/s over the 3 second interval.
