The final speed of C is equal to that of B.
The travel time of A is less than that of B.
The final speed of B is equal to that of A.
The travel time of C is greater than that of B.
The final speed of A is equal to that of C.
The travel time of C is greater than that of A.
<h3>What is speed?</h3>
The speed of any moving object is the ratio of the distance covered and the time taken to cover that distance.
Consider the three inclines shown in the figure (attached below). The vertical line is an incline with a 90° angle. All three inclines are frictionless. Three small identical objects are released from the top of the inclines.
When the objects are at the same height, they travel with the same height. The travel time is directly proportional to the incline.
Thus, all the statements are completed.

Answer:
The volume will not contract to one fourth of the original.
Explanation:
Applying Charles's Law as:
Given ,
V₁ = ?
V₂ = 2 L
T₁ = 5 °C
T₂ = 20 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (5 + 273.15) K = 278.15 K
T₂ = (20 + 273.15) K = 293.15 K
Using Charles law as:
Thus, the volume will not contract to one fourth of the original. (1/4 of 2 L is 0.5 L).
Explanation:
Plasma can conduct electricity because plasma consists of electrically charged particles called ions, instead of uncharged particles such as atoms or molecules.
Answer & Explanation:
A provisional patent application, also called a PPA, shows your invention as being in the process of getting a patent. This means that you will be safe from others copying your idea while your patent application is still being processed.
Answer:
1. They both uses same energy
2. The 6 kg ball requires more power than 3kg ball
Explanation:
Sample 1
m = 3kg
g= 10m/s^2
h = 2m
t = 2secs
W = mgh = 3 x 10 x 2 = 60J
P= w/t = 60/2 = 30watts
Sample 2
m = 6kg
g= 10m/s^2
h = 1m
t = 1sec
W = mgh = 6 x 10 x 1 = 60J
P= w/t = 60/1 = 60watts
They both uses same energy but different power. The 6 kg ball requires more power than 3kg ball
