Answer:
Explanation:
A plane mirror will produce a virtual image of a real object. But it is correct that a plane mirror will also produce a real image of a virtual object.A virtual image An image in a mirror is a virtual object, which can in turn be used to create another image. This can occur when you have more than one optical element in the optical system. Then the object of one component becomes the image of the next optical component.
So the answer is Yes it will!!!!
I don't exactly understand the substance of the question so im going to assume that the answer you are looking for is buoyancy. Buoyancy determines whether something sinks or floats in water. A ship has a larger buoyancy due to the shape of the hull, a nail is does not and will sink.
I am pretty sure that the molecule that has an unbalanced arrangement of charge is placed in the second option from the scale represented above - Nitrogen gas (a diatomic molecule, N2). This one looks the only proper. I hope you will agree with me. Regards!
Answer:
option (E) 1,000,000 J
Explanation:
Given:
Mass of the suspension cable, m = 1,000 kg
Distance, h = 100 m
Now,
from the work energy theorem
Work done by the gravity = Work done by brake
or
mgh = Work done by brake
where, g is the acceleration due to the gravity = 10 m/s²
or
Work done by brake = 1000 × 10 × 100
or
Work done by brake = 1,000,000 J
this work done is the release of heat in the brakes
Hence, the correct answer is option (E) 1,000,000 J
