Answer:
180000 N
Explanation:
According to Newton's law of gravitation
F= G m1 m2 / r^2
This expression shows that if distance is reduced to half the gravitational force will increase 4 times.
Explanation:
n=50,r=0.02mn=50,r=0.02m,
I=5AandB=0.20TI=5AandB=0.20T

=50×5×3.14×4×10−4×2×10−1=50×5×3.14×4×10-4×2×10-1
=6.28×10−2Nm=6.28×10-2Nm
Given τ=12×τmaxτ=12×τmax
⇒sinsinθ=12⇒sinsinθ=12 or sinθ=30∘sinθ=30∘
=∠betweenareavar→randmag≠ticfield=∠betweenareavar→randmag≠ticfield.
So angle between magnetic field and the plane of the coil
=90∘−30∘=60∘=90∘-30∘=60∘.

In 2006, the International Astronomical Union created a new category of object in the solar system. The first object to be listed in that category was Pluto, and several more have been discovered and included since then.
The category is "Dwarf Planet" .
To start, we need to know the formula for centripetal acceleration
In this problem, we know that the speed of the vehicle is 95 km/hr
We will need to convert that speed into m/s
95 km/hr = 26.3889 m/s
Second, we know that the diamater of the circular track is 1 km.
To find radius, we just take half of the diameter, which makes the radius 500 meters.
Now we have:
Velocity = 26.3889 m/s
& Radius = 500 meters
Plugging this into the centripetal acceleration formula yields us
a = (26.3889)^2/500 = 1.39 m/s^2
Answer:
<em>a. q=450 c
</em>
<em>b. E=675 J
</em>
Explanation:
<u>Direct Current (DC)
</u>
It's the flow of electric charges in one direction driven by a constant voltage circuit. The intensity of the current flow is computed as
Where q is the constant flow of charge in time t
The energy of an element providing Voltage V, current I during a time t is
a. The charge can be computed by solving the first equation for q
b. The energy transferred by the battery is
