The electromagnetic waves do not need any medium to travel as they are not mechanical in nature. They propagate in the form of electric and magnetic energy having a perpendicular vector of its velocity wave
Given the measured value of mass M in the experiment the error in 2M is ; dM
<u>Given data :</u>
Measured value of mass M = ( 0.743 ± 0.005 ) kg
<h3>The error in 2M in the measured value </h3>
The error in 2M in the measured value M = 0.743 ± 0.005 kg is dM while the error in M² will be 2dM
Hence we can conclude that the measured value of mass M in the experiment the error in 2M is ; dM.

Answer:
a = 129.663
Explanation:
We know that:
T = Ia
Where T is the torque, I is the moment of inertia and a is the angular aceleration:
First, we will find the moment of inertia using the following equation:
I =
Where M is the mass and R is the radius of the disk. Replacing values, we get:
I =
I = 0.904 kg*m^2
Second, we will find the torque using the following equation:
T = ()*(R)
Where is the force on one side and is the force on the other side. Replacing values, we get:
T = (162N-63N)(1.184m)
T = 117.216N*m
Finally, we replace T and I on the initial equation as:
T = Ia
117.216N = (0.904)(a)
Solving for a:
a = 129.663
Answer:
Explanation:
Therefore, the speed of the car is 63m/s after 8 seconds while accelerating at it maximum capability.
Answer:
<h3>The answer is 61,200 m</h3>
Explanation:
To find the distance covered by the dolphin , we use the formula
<h3>distance = velocity × time</h3>
From the question
velocity = 17 m/s
time = 3600 s
We have
distance = 17 × 3600
We have the final answer as
<h3>61,200 m</h3>
