The power resulting from the torque is 340.34 W. Explanation: The angular speed can be calculated as ω = (25/2)(rev/min)(2π rad/rev)(min/60s) = 1.308 rad/s. The torque applied is T = 260 Nm. The power can be found using P = T ω, therefore P = (260)(1.308) leads to P = 340.34 W, which indicates the power exerted by the torque of 260 Nm.

A 1,300 kg wrecking ball hits the building at 1.07 m/s2.
ValentinkaMS [2425]
We know that F=ma
where m represents mass and a indicates acceleration
thus, Force= ma
therefore, F=1300X1.07=1391N

Yuliya22 [2420]

Respuesta:

El cambio de temperatura en Celsius equivale a 46°C.

El cambio de temperatura en Fahrenheit equivale a 82.8°F.

Explicación:

Un grado Celsius es equivalente a un grado Kelvin; por lo tanto,

\Delta C = \Delta K = 283K-237K\\\\ \boxed{\Delta C = 46^oC}

Un grado Fahrenheit es 1.8 veces un grado Celsius; por lo tanto

\Delta F = 1.8(46^o)

\boxed{\Delta F = 82.8^oF}

Por lo tanto, el cambio en Celsius es de 46°C y en Fahrenheit es de 82.8°F.

A ball is dropped from the top of a building.After 2 seconds, it’s velocity is measured to be 19.6 m/s. Calculate the accelerati
Keith_Richards [2256]
The acceleration, a = 9.8 m/s². Explanation: The phrase 'A ball is dropped from the top of a building' implies that the ball's initial velocity is zero, u = 0 m/s. After 2 seconds, the ball's velocity measures 19.6 m/s, with t = 2s, v = 19.6 m/s. Employing the equation

v = u + at yields 19.6 = 0 + 2a, hence a = 9.8 m/s².
