I'm guessing that you mean like this:
-- The ruler is held with zero at the bottom, and the centimeter markings
increase as you go up the ruler.
-- You place your fingers with the ruler and the zero mark between them.
-- The number where you catch the ruler is the distance it has fallen.
Then, all we have to find is the time it takes for the ruler to fall 11.3 cm .
Here's the formula for the distance an object falls from rest
in a certain time:
Distance = (1/2) (gravity) (time)²
On Earth, the acceleration of gravity is 9.8 m/s².
So we can write ...
11.2 cm = (1/2) (9.8 m/s²) (time)²
or
0.112 meter = (4.9 m/s²) (time)²
Divide each side
by 4.9 m/s² : (0.112 m) / (4.9 m/s²) = time²
(0.112 / 4.9) sec² = time²
Square root
each side: time = √(0.112/4.9 sec²)
= √ 0.5488 sec²
= 0.74 second (rounded)
Answer:
N
N
Explanation:
= 1 A
= 4 A
= distance between the two wire = 5 m
= Force per unit length acting between the two wires
Force per unit length acting between the two wires is given as
N
= distance of each wire from the midpoint = 2.5 m
Magnetic field midway between the two wires is given as

because I did this assignment, :) your welcome
Next time do it by yourself, but here's the answer kid
An insurance company wants people to avoid risks because if the person meets with an accsident the expense of the medicines and treatment should be covered by the insurance company.
Answer:
DMM should be placed in the series combination with the circuit.
Explanation:
DMM is the digital multi meter. It can measure the voltage, current and resistance at a time.
- While measuring the current with the DMM you must be ensure that the DMM should be connected with the circuit in series combination. So that it will give the resultant current accurately.
- While measuring the voltage the observer should check the open probes.
