Below is an attachment containing the solution.
Hello!
A portable DVD player requires six 1.5-volt batteries to operate. If the resistance in the circuit is 7.2 ohms, what is the current?
Data:
We have six 1.5 volt batteries, soon, your tension (V)
V = 1.5 * 6 = 9 Volts
R (resistance) = 7.2 ohms
I (Current intensity) = ? (in Amps)
Solving (Ohm's First Law):
Answer:
The current is 1.25 amps

Answer:2.55 rad/s
Explanation:
Given
Diameter of ride=5 m
radius(r)=2.5 m
Static friction coefficient range=0.60-1
Here Frictional force will balance weight
And limiting frictional force is provided by Centripetal force
weight of object=mg
Equating two
f=mg

Jun 29, 2016 · Tectonic plates are large segments of the Earth’s crust that move slowly. Suppose that one such plate has an average speed of 4.0 cm/year. (a) What distance does it move in 1.0 s at this speed? (b) What is its speed in kilometers per million years?
Explanation:
The GPE or gravitational potential energy will be transfer into kinetic energy because the roller coaster have potential to go down the hill because of gravity.
It will be convert into kinetic energy
