Answer:
85.66m
Explanation:
Given the following data;
Horizontal velocity = 25.8m/s
Height = 54m
Initial velocity = 0
We would first of all, solve for the time taken using the formula for maximum height of a projectile.
H = ½gt²
Where;
- H is the maximum height measured in meters.
- g represents the acceleration due to gravity measured in meters per seconds square.
- t represents the time taken measured in seconds.
We know that acceleration due to gravity is 9.8m/s²
Substituting into the equation
54 = ½*9.8t²
54 = 4.9t²
t² = 54/4.9
t² = 11.02
t = 3.32 secs
To find the distance;
Distance, x = velocity * time
x = vt
Substituting into the equation, we have;
x = 25.8*3.32
x = 85.66m
Answer:
The rate at which temperature changes is proportional to the rate at which heat is transferred.
Explanation:
The temperature of a sample changes more rapidly if heat is transferred at a high rate and less rapidly if heat is transferred at a low rate
Answer:
Possibly shape.
Explanation:
Because it is ripped in half. As you guys and the questioner can see that there is a wiggly strip down the middle. That also cause of a shape change.
I really hope my answer is right ^_^
Power is the rate that work is done or work per unit time.
So doing more work per unit time creates more power.
Power = Work / time
Answer:
D. none of them.
Explanation:
This is because Ohm's law is:
Voltage = Current × Resistance
or,
V = IR
