Mass = kinetic energy * 2 / velocity^2
=> mass= 100 * 2 / 5^2
= 200 / 25 = 8 kg
in short , your answer is 8 kg
Answer:
the imparting or exchanging of information or news.
Explanation:
Answer:
0.25hr
Explanation:
Given parameters:
Distance = 200km
Time = 2hrs
Now, let us find the rate which is the speed;
Speed =
Insert parameters:
Speed =
= 100km/hr
Since the speed of Imamu = 2 x speed of Mosi = 200km/hr
Time taken =
=
= 0.25hr
Answer:
Therefore,
Current required is , I

Explanation:
Given:
Turns = N = 1140
length of solenoid = l = 0.415 m
Magnetic Field,
To Find:
Current , I = ?
Solution:
If N is the number of turns in the length, the total current through the rectangle is NI. Therefore, Ampere’s law applied to this path gives
Where,
B = Strength of magnetic field
l = Length of solenoid
N = Number of turns
I = Current
Therefore,
Substituting the values we get
Therefore,
Current required is , I
