Answer:
The linear speed of scratch is 45.55 cm/dec
Explanation:
The scratch located from the center at radial distance = 14.5 cm.
Each minute the skip of scratch when disco record played = 30 times
Since, the scratch on the disc start revolving when disc is played and in one minute the scratch revolve 30 times. Therefore, the revolution = 30 RPM
Below is the calculation of linear speed of the scratch.
0.000025 → 2.5 × 10⁻⁵ → 2.5E-5
<h3>Further explanation</h3>Scientific notation represents the precise way scientists handle exceptionally abundant digits or extremely inadequate numbers in the product of a decimal form of number and powers of ten. Put differently, such numbers can be rewritten as a simple number multiplied by 10 raised to a certain exponent or power. It is a system for expressing extremely broad or exceedingly narrow digits compactly.
Scientific notation should be in the form of
where
The number 'a' is called 'mantissa' and 'n' the order of magnitude.
From the key question that is being asked, we face the standard form of 0.000025.
The coefficient (or mantissa), i.e. 25, is still outside of 1 ≤ a < 10. Both the numerator and denominator are divided by 10.
The denominator consists precisely of five zero digits.
Hence, 0,000025 is written in scientific notation as
The inverse of scientific notation is the standard form. To promptly change scientific notation into standard form, we reverse the process, move the decimal point to the right or left. This expanded form is called the standard form.

Answer:
b Use a balance to determine the mass of the car. Use a motion sensor to measure the speed of the car at a time of 0s and at time of 5s .
Explanation:
The right way to measure the net force on the car is take the measurement of its mass then find the speed of the car within the time 0s to 5s.
This is because the net force acting on car is given as;
Force = mass x acceleration
By using the balance, the mass is determine
Acceleration is the rate of change of velocity with time.
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Now,
Force = mass x
