Answer:
so you have a question
Explanation:
either way have a nice day
Answer:
The mass of snow accumulated in the lawn in 1 hour equals 57.024 kilograms
Explanation:
Given
Width of lawn = 16 feet
Length of lawn = 20 feet
Thus total area of lawn equals
\
Now it is given that 1 square foot accumulates 1350 new snowflakes each minute thus number of snowflakes accumulated by 320 square feet in 1 minute equals

Now it is given that average mass of each snowflake is
Hence the mass accumulated per minute equals 
Now since there are 60 minutes in 1 hour thus the mass accumulated in 1 hour equals 
This thermal energy flows as heat within the box and floor, ultimately raising the temperature of both of these objects.
Answer:
1.31Kgms-1
Explanation:
∆p = m∆v
Where:
∆p= change in momentum
m= mass of the ball
∆v= change in velocity of the ball= (5.3-2.4)= 2.9ms-1
Therefore, substituting appropriately with the values above:
∆p= 0.45×2.9= 1.31Kgms-1
Answer:
-0,2 m/s²
Explanation:
Acceleration = α = (V-V₀)/t
α = (10-14)/20 = -0,2 m/s²
