Is W * SA joule?
A watt-second (symbol W s or W·s) is a derived unit of energy equivalent to the joule. The watt-second is the energy equivalent to the power of one watt sustained for one second.
How many joules is 50 watts?
How many joules of energy does a 100 watt?
E = P × t = 100 × 3600 = 36 × 10 4 J . Since the kinetic energy of the person is equal to the heat loss. E = 12mv2⇒36×104 = 12×70.0×v2⇒v2 = 2×36×10470⇒v = 1.0141×102 = 101.41 m/s. E = 1 2 m v 2 ⇒ 36 × 10 4 = 1 2 × 70.0 × v 2 ⇒ v 2 = 2 × 36 × 10 4 70 ⇒ v = 1.0141 × 10 2 = 101.41 m / s .
How many watts is 60000 joules?
