A student sees her physical science professor approaching on the sidewalk that runs by her dorm. She gets a water balloon and waits. When the professor is 2 s from being directly under her window 11 m above the idewalk, she drops the balloon. You finish the story. (Assume g # 10 m/s*)
Answers
Answer:Misses the Target
Explanation:
Given
Distance between window and Professor is h=11 m
she dropped the balloon 2 sec earlier
time taken by balloon to cover the 11 m
using
where h=height
u=initial velocity
t=time
a=acceleration
Therefore she misses the Professor by 0.51 s

Answers
Answer : speed
Explanation :
Speed is defined as the distance travelled per unit time. It is a scalar quantity.
Velocity is displacement covered per unit time. It is a vector quantity. This means it have both magnitude as well as direction.
When captain told the passengers that the plane is flying at 450 miles per hour, then this shows the speed of plane. He is not talking about the direction in which the plane is flying.
So, this information describes the speed of plane.
Correct option is (2).
If he had also told them what direction they were flying, then
they would have been able to put the two pieces of information
together, and they would know the plane's velocity.

I can't think of any way that pressure can be decreased due to added pressure.
Be that as it may, and it certainly still is ...
No matter what you do to the pressure or the temperature of
the gas in that tank, the volume doesn't change. Any sample
of gas always expands to fill the container in which it's confined.
Its volume doesn't change until you either transfer it to another
container with different volume, or else change the volume of
the container it's in.

Answers
Answer:
Because Moon and Mars has no atmosphere.
Explanation:
Moon and Mars has no atmosphere, so there is no friction on the falling object due to the atmosphere. The speed of the falling object is more at Moon and Mars.
When a small object impact on the surface of moon or Mars with high speed, the size of crater is large than the earth as out earth has atmosphere.
Final answer:
The largest craters on the Moon and Mercury are larger than those on Earth due to the Moon's and Mercury's geological inactivity, absence of substantial atmosphere, and lower frequency of erosional and tectonic processes. These conditions preserve the craters and allow for the conjecture of an impact origin of these features, as well as provide valuable clues into the historical events of the solar system.
Explanation:
The reason why the largest craters on the Moon and Mercury are much larger than the largest craters on Earth is primarily due to their geological and atmospheric differences. Both the Moon and Mercury are geologically inactive and lack substantial atmospheres. This means that their surfaces are not subjected to the same level of erosional processes present on Earth, like wind and water erosion, or tectonic activities that could erase or alter the appearance of craters over time.
Another important aspect is related to the frequency and scale of impact events. Crater formation rates on the Moon or Mercury can be estimated from the number of craters currently observable or from known quantities of existing cosmic debris (comets and asteroids), which can serve as potential projectiles. Given the extended geological timescales, large crater-forming impacts are relatively rare, occurring at a greater timescale than human history.
Furthermore, the size and shape of these craters often indicate an impact origin, as first proposed by prominent geologist Grove K. Gilbert in the 1890s. High velocity impacts result in explosive events that generate craters much larger than the size of the impacting body itself. Therefore, the size of lunar and Mercurian craters, as well as their count, can provide valuable insights into the history of our solar system.
