Answer:
speed and temperature
Explanation:
Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier weight the force with which an object near the Earth or another celestial body is attracted toward the center of the body by gravity. An object's weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull.

______________________________
1. temperature
2. increasing heat
3. its temperature begins rising from -20 C
4. it stops rising and stays steady at 0 C; the ice is using the
added heat to change state, melt, and turn to liquid
5. between 0 C and 100 C
6. it stops rising and stays steady at 100 C; it's being absorbed
by the water, and the water is using it to change state, evaporate,
and turn to gas
7. the heat is making the molecules move around easier
Answer:
T = 27.92 N
Explanation:
For this exercise let's use Newton's second law
T - W = m a
The weight
W = mg
The acceleration can be found by derivatives
a = dv / dt
v = 2 t + 0.6 t²
a = 2 + 0.6 t
We replace
T - mg = m (2 + 0.6t)
T = m (g + 2 + 0.6 t) (1)
Let's look for the time for the speed of 15 m / s
15 = 2 t + 0.6 t²
0.6 t² + 2 t - 15 = 0
We solve the second degree equation
t = [-2 ±√(4 - 4 0.6 (-15))] / 2 0.6
t = [-2 ±√40] / 1.3 = [-2 ± 6.325] / 1.2
We take the positive time
t = 3.6 s
Let's calculate from equation 1
T = 2.00 (9.8 + 2 + 0. 6 3.6)
T = 27.92 N
<h2>T
he average speed for the entire trip is 47.5 m/s .</h2>
It is given that for different time span car have different speed and also the person spend in eating lunch and buying gas.
We know , average speed is total distance covered by total time taken .
Therefore , average speed ,
Hence, this is the required solution.

According to the chart concluded by Charity's observation, her rabbit prefers lettuce over celery and carrots and majority of rabbit species follows the same.
Answer: Statement A
<u>Explanation:</u>
As per the biological observations, it's is proven that leafy vegetables such as lettuce is worth for rabbits health as compared to carrots being involved in their daily diets as it contains sugar. According to the observations that Charity has gone through a month for her pet rabbit, it seems that her rabbit is most likely preferring lettuce over carrots and celery.
Talking about celery, it's not among the leafy kinds of rabbit's diet and should only worth of only 15% of space in daily diet. Although rabbits often eat celery, but most of the species primarily rely on lettuce and parsley which seems the case with Charity's pet. Hence, the statement A is likely to be the best answer according to the observations that the rabbit prefers lettuce over carrot and celery.
