X-rays are high energy electrons
that can cause damage when exposed under extreme conditions. The best technology
that can block it is using a lightweight type of metal foam. It can take in
high energy collisions which also exhibits high forces. it does not only block
x-rays but also, neutron radiation and gamma rays.
Answer: Acceleration due to gravity
Explanation: Force, F = mg, is a vector quantity because the acceleration due to gravity, g, is a vector quantity. Explanation: F = mg Where m is the mass (in kilograms) of the object in question and g is the acceleration due to gravity. Mass is a scalar quantity; mass has no dependence on direction whatsoever.
The leaf fell at the crooked path instead of straight down because air currents and gravity applied changing and unbalanced forces to the leaf.
<h3>What is an air current?</h3>
An air current is defined as the changes in atmospheric pressure that causes the movement of air from one area to another.
When a leaf is detached naturally from the tree, it won't fall straight down to the floor but will fall a distance away from the tree due to the action of air current and some unbalanced forces.

Answer:
Magnetic field, B = 0.88 T
Explanation:
It is given that,
The dimension of rectangular surface is 2.80 cm by 3.15 cm. The area of rectangular surface is, 
Angle between the uniform magnetic field and the horizontal, 
Magnetic flux, 
Let B is the magnitude of magnetic field in which the rectangular surface is placed. It is given by :
is the angle between magnetic field and the area
Here, 
B = 0.88 T
So, the magnitude of magnetic field is 0.88 T. Hence, this is the required solution.
