Answer:
c) The distance between the balls increases.
Explanation:
If you drop the balls at the same time, regardless of their masses they accelerate equally, since they will be in free fall.
However, if you drop one of the balls earlier, then that ball will gain velocity, whereas the second ball has zero initial velocity. At the time the second ball is dropped, both balls have the same acceleration but different initial velocities.
According to the below kinematics equation:
The initial velocity of the first ball will make the difference, and the first ball will travel a greater distance than the second ball. Hence, their distance increases.
Answer:
A. .
Explanation:
By definition of Electric Capacitance, the capacitance of the system (), in farads, is described by the following formula:
(1)
Where:
- Electric charge, in coulombs.
- Voltage, in volts.
If we know that and
, then the capacitance of the system is:
The correct answer is A.
Answer:
Explanation:
Ball rises and falls in equal periods. Because it goes by same speeds and same route. Therefore t_{rise} = t_{fall} =2.5 s
In free fall and vertical throw movement: x= (1/2).a.t^{2}
Here, we can find the height of the ball
x= (1/2).5.(2.5^{2}) = 15.625 m
From the attaches V-t graphics, x=V.t/2
15.624=V.(2.5)/2
V=12.5 m/s
The child at 5 years old would weight: 60 lb (27.16 kg) If he continues gaining weight a that rate
To solve this problem we will use a rule of three with the problem information:
3 years-------- 36 lb child's weight
5 years -------- x
Applying the rule of three we get:
x = ( 5 years * 36 lb child's weigh) / 3 years
x = 60 lb
By converting the weight units from lb to kg we have:
x = 60 lb * 16.3 kg/36 lb
x = 27.16 kg
<h3>What is rule of three?</h3>It describes the proportionality of 3 known data and an unknown data. When you have more than 3 known facts that are involved in the proportionality, it is known as a compound rule. The rule of three is also known as a direct proportions.
