Answer:
effort required to lift the box off the ground using a 3m long lever=2N
Explanation:
In this question we have given
force required,F=10N
mass of box.m=10kg
length of lever, l=3m
distance between fulcrum and box,d=.5m
effort required to lift the box off the ground using a 3m long lever=?
Here,
Effort required to lift the box off the ground using a 3m long lever
Effort required to lift the box off the ground using a 3m long lever
Effort=
Effort=2N
Answer:
The magnitude of the magnetic field made by current in the wire is 3.064 x 10⁻⁶ T.
Explanation:
Given;
length of the straight wire, L = 0.56 m
conventional current, I = 0.4 A
distance of magnetic field from the wire, r = 2.6 cm = 0.026 m
To determine magnitude of magnetic field made by current in the wire, we will apply Bio-Savart Law;
Therefore, the magnitude of the magnetic field made by current in the wire is 3.064 x 10⁻⁶ T.
Answer:
Explanation:
From the question we are told that:
Speed of light
Generally the equation for Average Speed is mathematically given by
Where
d=Distance between the Earth and the sun
Therefore
Since m and n is given in the form of
Therefore
