Answer:
A ramp
Explanation:
An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists.
Answer:
Electric Field at a distance d from one end of the wire is
Electric Field when d is much grater than length of the wire =
Explanation:
Given:
- Total charge over the length of the wire = Q
- Length of the wire = L
- Distance from one end of wire at which electric field is needed to find=d
Let dE be the Electric Field due to the small elemental charge on the wire at a distance x from the one end of the wire and let be the charge density of the wire
Now integrating it over the entire length varying x from x=d to x=d+L we have and replacing we have
When d is much greater than the length of the wire then we have
1+\dfrac{L]{d}≈1
So the Magnitude of the Electric Field at point P =
Explanation:
the objects having very small masses and greater distance between them.........you will understand better using the newtons law of gravitation
which states that
F=m₁m₂/r²
this clearly shows that smaller are the masses smaller would be the force of gravitation and vice versa......
Answer:
-Spherical Concave mirror
-distance is 0.1368 m
Explanation:
-In physics, magnification is defined as the ratio between the size of the image to the size of the object;
This is also same as;
Given that m=95x, and and the image distance as 13m, the object distance is calculated as:
Hence, the object distance is 0.1368 meters
The image grows bigger when object is moved closer to the mirror, hence , this is a spherical concave mirror
