The gravitational forces are the same. (C).
1 kg is 1 kg. It always has the same weight, no matter whether it's made of kryptonite, concrete, or chicken soup.
If I sealed the kg of lead and the kg of marshmallows into two different boxes, you couldn't tell any difference.
Answer:
The speed of the car is 32.4m/s
Explanation:
1mi = 1600m
152mi = 243 200m
2hr 5min = 7200s + 300s
= 7500s
speed = distance/time
= 243200/7500
= 32.4m/s (3s.f)
1. A teacher challenges.students to study moon phases to determine if what they have learned from the textbook is accurate. How might a student investigate claims made in a textbook that moo. phases occur in a 28-day cycle?
A. observe the phase of the moon each night until a full moon can be seen.
B. Compare the textbook phases to the actual moon phases seen in the night sky each night in 28 days periods over a three month time frame.
C. Compare diagrams of moon phases from the textbook to diagrams of moon phases on-line
D. Observe the moon phases seen in the night sky as often as possible over a six month period.
2. What causes the apperance of the moon change overtime?
A. The orbit of the Earth around the Moon and its distance from the sun.
B.The Moons position relative to the sun and earth as it revolves around sun.
C. the rotation of the moon on its axis
D. The distance of the moon to the sun

At point B, the substance undergoes deposition, transitioning directly from a gas phase to a solid phase. The correct option is a.
At point B on the phase diagram, the phase transition occurring is deposition. Deposition is a physical process in which a substance transitions directly from a gas phase to a solid phase without passing through the liquid phase. This change is driven by a decrease in temperature or an increase in pressure.
During deposition, gas particles lose energy, causing them to slow down and come together to form a solid structure. This process is exemplified in nature when water vapor in the atmosphere turns directly into frost or ice crystals on a cold surface. Deposition is the opposite of sublimation, where a substance transitions from a solid to a gas without becoming a liquid.

option C is correct answer.
The dog whistle is manipulating frequency. This is further explained below. Option B is correct.
The sound of a high-pitched sound is harsh and has a high pitch. Examples are:
In conclusion, for a high pitch, we alter the frequency.

Answer:
Frequency
Explanation:
(I believe don't count me on this) Amplitude is the wave height otherwise known as how loud it is or the maximum displacement of vibrating particles
