F
From among the choices provided, the better choice is the upper-case letter 'T '. That symbol can conveniently be used to represent the words "true" or "truth", which is exactly the reason that it is the better choice for a response, since the complicated statement at the beginning of the question is completely true in its every detail, nuance, jot and tittle.
Answer:
it is true my child
Explanation:
Answer: (D). The unit and direction is missing.
Explanation:
Velocity: Velocity is the speed of the object with direction and it is the vector quantity. The unit of velocity is m/s.
Average velocity: Average velocity is defined as the total distance divided by the total time.
Here,
D = Total distance
T = Total time
According to the question:
The unit and the direction is missing in the cyclist's velocity.
Hence, The unit and direction is missing.
Answer : The momentum is, 357 kg.m/s
Explanation :
Momentum : It is defined as the motion of a moving body. Or it is defined as the product of mass of velocity of an object.
Formula of momentum is:
where,
p = momentum
m = mass = 75.0 kg
v = velocity = 5.00 m/s
Now put all the given values in the above formula, we get:
Therefore. the momentum is, 357 kg.m/s
75 kg × 5 m/sec = 375 kgm/s
Hope this helps :)
Answer : The correct option is water.
Explanation :
Water has an ability to absorb large amount of energy without changing temperature very much.
This shows the specific heat of water is high. It is approximately equal to .
The specific heat of air is .
The specific heat of concrete is .
The specific heat of soil is .
So, the correct option is (C) " water ".
B.a quantity with both magnitude and direction
C.a magnitude described as a number
D.the magnitude of a value
