Answer:
400X
Explanation:
Total magnification = power of eyepiece (ocular) × power of the objective lenses
= 10X × 40X = 400X
There are three fundamental forces that act at a distance. They are gravitational, electromagnetic and nuclear forces.
Answer:
123.61 J
Explanation:
PE = KE
mgh = 1/2 mv2.
(2.80)(9.81)(4.50)=123.606J
Answer:
The trouble that the most recent experiment, Borexino, have to overcome was that
neutrinos hardly interact with matter and so radioactive decay of ant material inside the detector could look exactly like a neutrino interaction too
Explanation:
Given parameters:
Power of the toaster = 600W
Voltage = 120V
Unknown:
Current = ?
Resistance = ?
Solution:
The power in the circuit is related to resistance and current using the expression below;
P = IV
P =
P is the power
I is the current
V is the voltage
R is the resistance
To find the current;
I = = = 5A
Now, resistance;
V² = PR
R = = = 24ohms
