How can one object affect the motion of another without touching it? Give a specific example.
Answers
There are two types of forces
1. Physical force : in this type of forces we require direct contact between two bodies
2. Field force: here we do not requires any type of physical contact with the body
so here in this type of field force we do not required any contact but only due to field present near it the body can move
so here several examples are there
a) when a magnet is placed near a piece of iron then it will move towards the iron
b) a positively charged particle when come near another charged particle then it will get attracted or repelled.
so as per all above discussion we can say that an object can move without any direct contact
Final answer:
Objects can affect the motion of others without touching through the force of gravity. For example, the Moon affects the tides on Earth.
Explanation:
One way that an object can affect the motion of another without touching it is through the force of gravity. Gravity is a long-range force that acts between all objects with mass. For example, the Moon affects the motion of the tides on Earth without physically touching the water.

Answer:
3. Usinθ
Explanation:
The vertical component of velocity of any object reaching maximum height is 0 and the horizontal component of velocity of any object in flight remains constant.
Therefore the horizontal component of velocity is Ucosθ for both objects at any given time.
At maximum height A is having 0 vertical velocity but B which just starting its flight is having Usinθ as its vetical component of velocity.
Velocity of B relative to A = Velocity of B - Velocity of A
As velocity can be resolved to components,( to simplify the sum )
Horizontal component of velocity of B relative to A = Horizontal component of velocity of B - Horizontal component of velocity of A
which is 3. Usinθ

Answer:
The answer is not correct.
Explanation:
Stu's answer is not correct, the equation to use is known as the law of ohm. In which the voltage is defined as the product of the current by the resistance, then we will see this equation.
In order to find resistance, this term is found multiplying the current on the right side of the equation, therefore the current will be divided on the left side of the equation.
That is the reason that the result found by Stu is not correct.
Answer:
Sample Response: Stu's answer was incorrect. According to Ohm's law, R = V/I. This is the equation that should be used to obtain the correct answer, which is 8 ohms.

The answer is: volcano.
Explanation:
The mid-ocean ridges are underwater elevations located in the middle part of the Earth's oceans.
The chain has a very rugged relief, with wide slopes and ridges often marked by a deep longitudinal recess, called the sinking or rift valley, along which numerous surface earthquakes and volcanic eruptions occur that pour basalt lavas.
The answer is: volcano.
