Answer:
Although the gravitational force the Earth exerts on the objects is different, their masses are just as different, so the effect we observe (acceleration) is the same for each. The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.
What was the caloric theory of heat?
Answer:Caloric theory, explanation, widely accepted in the 18th century, of the phenomena of heat and combustion in terms of the flow of a hypothetical weightless fluid known as caloric. ... The idea of an imaginary fluid to represent heat helped explain many but not all aspects of heat phenomena.

An engineering team has come to the stage in the engineering design
process in which it is iterating to improve the solution. What is one thing they
might be doing?
A. Identifying different sets of criteria and constraints to use for each
possible solution
B. Choosing one solution to model out of many possible solutions
the team has identified
C. Identifying the limits on how the prototype can be used to solve
the engineering problem
D. Making improvements to the original prototype in order to perform
more tests
Answer:
D. Making improvements to the original prototype in order to perform
more tests
Explanation:
just did it
The one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.
What is prototype?Prototype is defined as a type of early version, or initial release of a product created to test a theory or procedure.
It can be defined as a test procedure where design teams put concepts into concrete forms, whether they be paper or digital.
It can also be defined as a useful tool for the creation of new products. It provides the creative with the opportunity to watch their concept come to fruition.
There are three basic rule of prototyping.
Inquire as to who will gain.Fail frequently and early.Use show and ask instead of show and tell.When the EGL system code does not have access to the function itself, a function prototype definition is used to provide type checking on function calls.
Thus, the one thing that they might do is making improvements to the original prototype in order to perform more tests. Thus option D is correct.

A cricket batsman hits a ball at a speed of 27m/s at an angle of 60 degrees to the horizontal. How far away would you have to stand in order to catch it (assuming you want to catch it just before it hits the ground)?
Answer:
64.4 m
Explanation:
First, find how long it takes to land. Given in the y direction:
Δy = 0 m
v₀ = 27 m/s sin 60° ≈ 23.4 m/s
a = -9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
0 m = (23.4 m/s) t + ½ (-9.8 m/s²) t²
t = 4.77 s
Next, find how far it travels in that time. Given in the x direction:
v₀ = 27 m/s cos 60° = 13.5 m/s
a = 0 m/s²
t = 4.77 s
Find: Δx
Δx = v₀ t + ½ at²
Δx = (13.5 m/s) (4.77 s) + ½ (0 m/s²) (4.77 s)²
Δx = 64.4 m

What is the momentum of A 200 kg shark swimming at 15 m/s? bruh please help im failing and dont understand this:)
Answer:
p = 3000 kg-m/s.
Explanation:
Given that,
Mass of shark, m = 200 kg
Speed of the shark, v = 15 m/s
We need to find the momentum of the shark. It can be calcullated as follows :
p = mv[tex]p=200\ kg\times 15\ m/s\\\\p=3000\ kg-m/s[/tex]
So, the momentum of the shrak is 3000 kg-m/s.
A motorcycle is stopped at a traffic light. When the light turns green the motorcycle accelerates to a speed of 77 km/h over a distance of 50 m.
(a) What was the average acceleration of the motorcycle over this distance?
(b) Assuming the motorcycle maintained a constant acceleration, how far is it from the traffic light after 3.0 s?
Answer:
good luck
Explanation:
.....................
whats the average velocity
Answer:
A velocity is a vector unit, and average velocity can be described as the displacement divided by the time. The units for velocity can be understood from the definition to be meters/second or in common any distance unit over any time unit. The average speed of a body is described as the distance covered divided by the time elapsed.
Explanation:
the force of speed
Answer:
10 m/s
Explanation:
The average velocity is the slope of the graph.
m = (10 - 0)/(1 - 0)
m = 10/1
m = 10 m/s

Explanation:
Complete the paragraph to describe binary systems. A binary star system is made of (blank) stars, one of which is brighter than the other. Astronomers are able to detect the dimmer star because its gravity causes the bright star to (blank). Astronomers can also spot the dimmer star by observing a phenomenon called a(n) (black) binary. This happens when the dim star passes in front of the bright star.
