Answer:
The mass of the cart is 26.7 kg.
Explanation:
To find this answer use the formula for acceleration first to find how fast the object had to be acccelerating to gain a velocity of 45m/s in 8 seconds flat.
Here's the formula for acceleration:
a = V- V₀ ÷ T (Wher V = final velocity; V₀ = Initial velocity, and T = time)
Plug all known values into the equation and you get -
a = (45m/s - 0m/s) ÷ 8 , which works out to 5.625 m/s²
Once you have this value then you place it into the equation for finding an object's mass, and that formula is:
M = or M =
This works out to 26.6667 kg or approx. 26.7 kg if you are asked to round it to three significant figures.
First degree burns only damage the epidermis. This could cause the skin to lose their protective effect. One of the important function of the skin is to prevent the loss the water and prevent infection.
The damaged epidermis can loss water molecule, makes the patient prone to dehydration.
The skin also at risk for infection as the bacteria can easily grow and damage the skin.
