The greatest common factor is 2.
Answer:
The ball will be overtake superman after travelled distance 248.5 m.
Explanation:
Given that,
Speed of superman = 35 m/s
Height = 330 m
Mass of ball = 10 kg
Let the height at which they are at same position be S.
For superman,
We need to calculate the time
Using equation of motion
...(I)
For ball,

From equation (I) and (II)




Put the value into the formula


We need to calculate the distance travelled
Using formula of distance

Put the value into the formula


Hence, The ball will be overtake superman after travelled distance 248.5 m.
Answer:
1.2kV
Explanation:
We are given that
Linear charge density,



We have to find the potential difference between poinst 5.0 m and 6.0 m from the wire.
We know that potential difference of wire

Where

Substitute the values



1kV=1000 V
Answer:
287.19 kg.m²
Explanation:
Given that :
The mass M of the horizontal platform = 111 kg
The radius R of the uniform disk = 1.67 m
mass of the person standing
= 64.7 kg
distance of the person standing
= 1.15 m
mass of the dog
= 25.7 kg
distance of the dog
= 1.35 m
Considering the moment of inertia of the object in the system; the net moment of the inertia can be expressed as:
= 
= 
= 287.19 kg.m²
Answer:
Diverging lens
Explanation:
A nearsighted person is a person who can not see the objects which are far away at infinity since the image is formed in front of the retina of the faraway objects. Therefore, a diverging lens is prescribed which can diverge the image to form the image at the retina.
Therefore, we need a diverging lens to correct the vision of nearsighted.
