Answer:
W'=125.44 N
Explanation:
The weight of a person on the surface of Earth is 784 N
Weight is given by :
W = mg
m is mass of the person and g is acceleration due to gravity on the surface of Earth (10 m/s²)
The acceleration due to gravity on the surface of Moon, g' = 1.6 m/s²
Weight of the person on the moon is :
W'=mg'
Hence, the person would weigh 125.44 N on the Moon.
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!!!!
Answer:
0.36s, 2.3s
Explanation:
Let gravitational acceleration g = 9.81 m/s2. And let the throwing point as the ground 0 for the upward motion. The equation of motion for the rock leaving your hand can be written as the following:
where s = 4 m is the position at 4m above your hand. 
is the initial speed of the rock when it leaves your hand. g = -9.81m/s2 is the deceleration because it's in the downward direction. And t it the time(s) it take to get to 4m, which we are looking for
t = 2.3 or t = 0.36
Answer: large reflector located in orbit above the Earth's atmosphere
Explanation:
Since the student wants to see the big weather patterns in the upper atmosphere of the planet, and she will therefore need to have excellent resolution, the type of telescope that is ideal for her to use is a large reflector located in orbit above the Earth's atmosphere.
It should be noted that the refractor or a radio telescope isn't ideal in this situation as they will not capture the bug weather pattern and doesn't have an excellent resolution like the large reflector.
