A joule is also called a newton metre so it is force in newtons multiplied by distance. Answer 3 seems to fit, assuming dm means “delta m” or a measure of the change of distance in metres.
An electric motors works by allowing the flow of electricity to flow throughout the system from the power source to the desired area. The motor is usually used to power other things and/or machines.
Answer: Metallic bonds between tin ions cause a sheet of tin to be malleable
Explanation:
The terminal speed of the marble is 0.588 m/s.
Given:
We know that,
F = mg ......(1)
where,
F = force
m = mass
g = acceleration due to gravity
Also,
v = F/k ......(2)
where,
v = terminal speed
k = proportionality constant
Substituting the value of F from equation (1) in equation (2)
v = mg/k .......(3)
Given,
m = 30 g = 0.030 kg
k = 0.500 kg/s
g = 9.8 m/s²
To find,
v =?
Put the values in equation (3)
v = mg/k
v = 0.03(9.8)/ 0.500
= 0.294/0.500
= 0.588 m/s
