I think it is this because compression stroke it needs to be compressed then open up when started.
Given:
The average temperature of the outer space near the earth is T_f=50.3 °F
To find:
Convert the given temperature to kelvin(K)
Explanation:
The temperature can be converted from degree Fahrenheit to kelvin using the formula,
On substituting the known values,
Final answer:
Thus 50.3 °F is equal to 283.17 K
<h2>The atomic mass of silicon is 28.0855</h2>
Answer:
Correct answer: m = 1,160 kg
Explanation:
Given:
P = 104 hp = 77.48 kW = 77.48 · 10³ W
V₁ = 21 m/s Initial speed (velocity)
V₂ = 29 m/s Final speed (velocity)
t = 3 seconds The time interval during which the work was performed
m = ?
The formula for calculating power is:
P = A / Δt
Since work is a measure of energy change in this case kinetic:
P = ΔEk / Δt = (Ek₂ - Ek₁) / Δt = (m V₂²/ 2 - m V₁²/ 2) / Δt
P = m · (V₂² - V₁²) / 2 · Δt ⇒ m = (2 · P · Δt) / (V₂² - V₁²)
m = (2 · 77.48 · 10³ · 3) / (29² - 21²) = 464.88 · 10³ / (841 - 441)
m = 464.88 · 10³ / 400 = 1.16 · 10³ = 1,160 kg
m = 1,160 kg
