naturally occurring radioactive elements have been around since the Earth's formation
Answer:
Explanation:
Trypophobia is a fear or disgust of closely-packed holes. People who have it feel queasy when looking at surfaces that have small holes gathered close together.A person may start by imagining what they fear, then looking at pictures of the fear object, and then finally being near or even touching the source of their anxiety. In the case of trypophobia, a person with symptoms may start by simply closing his eyes and imagining something such as a honeycomb or seed poThey can help you find the root of the fear and manage your symptoms.

You have the correct formula. Work = F d .
You use it by gathering up 'F' and 'd' and throwing away everything else.
F = 599.79 N
d = 153 cm
That's all you need to calculate 'W' with your formula. Just because they
also gave you the mass and the time doesn't mean you MUST use them.
My guess is that there are more parts to this problem where you may need
the mass and the time. For example, if they ask you for the power, then
you'll need to divide the work by the time.
To solve this problem we will use the theorems related to the conservation of momentum to determine the final speed of the system, once the bullet hits it. From there, we will calculate with the kinematic equations of linear motion, the height traveled with that speed. The conservation of momentum say us that,
Where,
mass of bullet
mass of block of wood
Initital velocity of bullet and block of wood respectively.
Final velocity
Our values are given as,
Replacing we have that
Note that the initial velocity of wood block is 0 because is at rest
Now using the kinematic equation of motion we have that
As 
Therefore the height reached by block after bullet embedding in it is 0.49 m
