Answer:
Explanation:
Assuming the crate does not lift above the ground and remains along the floor, then its acceleration will be in the horizontal direction. Therefore, we can use Newton's second law to find its acceleration:
where
is the net force on the crate along the x-direction
m is the mass of the crate
is the acceleration
Here we have:
m = 50.0 kg
is the component of the pulling force along the horizontal direction
Solving for the acceleration,
Answer:
In chemistry and physics, a valence electron is an outer shell electron with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Answer:
Explanation:
Given data:
Thickness of aluminium sheet 10 cm
initial temperature = 25 degree celcius
Assumption
Thermal properties remain constant, transfer of heat by radiation is negligible.
from the information given in the question we have
T_S ≈T_∞ , it implies we have h → ∞
from table 4.2 Biot number → ∞ the value of
The fourier number is
Temperature at center after 15 second of heating
Answer:
The b-b at rest will hit the ground first
Explanation:
When the first b-b is shot at angle it will first experience some horizontal force of air resistance before it experience another vertical force of resistance when going done while the second b-b only experiences the vertical force of resistance making reach the ground faster.
