Determine the values of mm and nn when the following average magnetic field strength of the Earth is written in scientific notat
joja [24]

Answer:

m = 4.51 and n = -5              

Explanation:

The average magnetic field strength of the Earth is 0.0000451 T. We need to write the value of magnetic field strength of the Earth in scientific notation. In scientific notation, any value is given by :

N=m\times 10^n.........(1)

Where

m is a real number

n is any integer

Here,

N=4.51\times 10^{-5}.......(2)

On comparing equation (1) and (2), we get the values as :

m = 4.51 and n = -5

Hence, this is the required solution.

7)An object is thrown straight up with an initial velocity of 3 m/s. What is its acceleration at its maximum height?
ser-zykov [4K]
C.
It is a motion with uniform acceleration, meaning that the acceleration will not change.
The object is thrown upwards with a positive velocity. This shows that the upward direction is positive. The object will decelerate due to gravity at a magnitude of 9.81 m/s2. Therefore, the acceleration is -9.81 m/s2.
Note that even though the velocity of the object is momentarily 0 m/s at maximum height, there is still a constant acceleration.
This allows the object first decelerate upwards, then change direction at max height, and finally accelerate downwards. So in this case, the acceleration is always negative and unchanged.
