Explanation:
It is given that,
Mass of an object is 13 kg
We need to find the mass of this object on the surface of Jupiter.
The mass of an object is the amount present in it. It it independent of location. It mass remains the same at Jupiter as well. Its does not depend on the gravity on that surface.
Hence, its mass will remain 13 kg on the surface of Jupiter.
Answer:
12.56 A.
Explanation:
The magnetic field of a conductor carrying current is give as
H = I/2πr ............................... Equation 1
Where H = Magnetic Field, I = current, r = distance, and π = pie
Making I the subject of the equation,
I = 2πrH............... Equation 2
Given: H = 1 T, r = 2 m.
Constant: π = 3.14
Substitute into equation 2
I = 2×3.14×2×1
I = 12.56 A.
Hence, the magnetic field = 12.56 A.
The longest bone in a human body is the Fumer (thigh bone)
Answer:
D.
Explanation: Both have shapes determined by gravitational forces.
<u>Explanation for the given picture:</u>
Initially, three principles of movement proposed by Sir Isaac Newton in 1686 "Principia Mathematica Philosophiae Naturalis". The third law says that every action (force) in nature has an equal but has opposite reaction.
In other words, when object A produces force on object B, then this object B also exerts the same but opposite forces on object A. Remember that forces get exerted on various objects. For example, if we put a wooden block in the floor, this block will create a force that should be equal to its mass, W = mg, which will work down.
The photo above clearly shows a person jumping off a tree on a wooden board, and therefore bouncing on the board because of the force exerted by the wooden board. Newton's third law is important if a person uses his power as weight (W = mg), and this in turn turns the person upside down! hence
Newtons 3rd law applies in above picture.
