Heat energy and thermal energy are the same because heat energy is thermal energy. Also thermal energy and temperature are the same because temperature is measuring heat in degrees Celsius or degrees Fahrenheit. Hope this helps!
Answer:
1m= 3.2 feets
? = 5280 feets
let ? be n
cross multiply
3.2n = 1×5280
n= 5280÷3.2
n= 1650
so, 5280 feets is equal to 1650 metres

Answer:
Explanation:
The impulse equation is
Δp = FΔt, where Δp = final momentum - initial momentum, F is the Force exerted on an object, and Δt is the change in time. In this equation,the entire right side defines the impulse. In other words, FΔt is the impulse; thus the change in momentum an object experiences is due to its change in impulse and is directly proportional to it.
Therefore, once we find the change in momentum, that is the impulse the object experiences. Δp = final momentum - initial momentum, where
p = mv and p is momentum.
so
and
so
; therefore,
Δp = 25.0 - 17.5 = 7.5
which is the unit for momentum
Answer:
9.2 m/s
Explanation:
v^2 = u^2 + 2as
u = 4.71
a= g * sin(8.30)
v= sqrt( 4.71^2 + 2 * 9.8* sin( 8.30 deg) * 22) = 9.2 m/s
