Answer:

d. 1 \times 10^{5} kilometers per hour

Explanation:

Halley's comet is named after the astronomer Halley. This comet entered the inner solar system from the Kupier's belt.  It is very large in size. It appears every 75 or 79 years in the inner solar system and can be seen with the naked eye. Its orbit is elliptical in shape. It reflects the sun light, otherwise it is entirely dark and made up of volatile material, as observed

Identify the normal force on the shopping cart after 75 newtons of groceries are added to the cart
Anna71 [15]
If the shopping cart is parallel to the ground, the weight is acting vertically downward, then force is equal to weight. The normal force will be acting perpendicular to the ground,and acting upward opposite of the weight.

One piece of copper jewelry at 111°C has exactly twice the mass of another piece, which is at 28°C. Both pieces are placed insid
vladimir2022 [97]

Answer:

83.33 C

Explanation:

T1 = 111 C, m1 = 2m

T2 = 28 C, m2 = m

c  = 0.387 J/gK

Let the final temperature inside the calorimeter of T.

Use the principle of calorimetery

heat lost by hot body = heat gained by cold body

m1 x c x (T1 - T) = m2 x c x (T - T2)

2m x c X (111 - T) = m x c x (T - 28)

2 (111 - T) = (T - 28)

222 - 2T = T - 28

3T = 250

T = 83.33 C

Thus, the final temperature inside calorimeter is 83.33 C.

What is hooke's law? Also what does it say about how elastic materials respond to force? Explain.
gogolik [260]
It <span>states that the force F needed to extend or compress a spring by some distance X is proportional to that distance.

For elastic materials, they extend more in same amount of force, (as they are directly proportional), due to it's elastic nature (presence of large deforming force)

Hope this helps!</span>
