Answer:
d
Explanation:
the heat can move through the metal and onto the clothing
They attract and stick together
The force is -12,000 N
Explanation:
First of all, we calculate the acceleration of the ball, by using the following suvat equation:

where:
v = 0 is the final velocity of the baseball (it comes to rest)
u = 40 m/s is the initial velocity
a is the acceleration
s = 2.0 cm = 0.02 m is the displacement of the ball
Solving for a,

Now we can calculate the average force exerted on the ball, by using Newton's second law:

where
m = 300 g = 0.3 kg is the mass of the ball
is the acceleration
Substituting,

where the negative sign indicates that the direction of the force is opposite to the direction of motion of the ball.

Answer:
Pressure of woman will be 
Pressure of the elephant will be 
Explanation:
We have given that mass of the woman m = 80 kg
Acceleration due to gravity 
Diameter of shoes = 1 cm =0.01 m
So radius 
So area 
We know that force is given F = mg
So 
Now we know that pressure is given by 
Now mass of elephant m = 5500 kg
So force of elephant = 5500×9.8 = 53900 N
Diameter = 20 cm
So radius r = 10 cm
So area will be 
So pressure will be
