Answer:

1,355.616Joules

Explanation:

The Amount of energy required is expressed as;

Q = mcΔt

m is the mass of water = 36g

c is the Specific heat of water = 4.184

Δt is the change in temp = 9 degree C

Substitute into the formula

Q = mcΔt

Q = 36(4.184)(9)

Q = 1,355.616Joules

The amount of heat required is 1,355.616Joules

A piston in an internal combustion engine applies torque during 150° of each full rotation of the crankshaft to which it is conn

aalyn [17]

Answer:

T=1.566 N.m

Explanation:

Given that:

rotational speed of the scrank shaft, N = 2500 rpm

power produced by one cylinder, P = 410 W

We know, in case of rotational power:

$P=\frac{2\pi.N.T}{60}$

where: T= torque

Substituting the respective values in the above eq.

$410=\frac{2\pi\times2500\times T}{60}$

$T= \frac{410\times60}{2\pi\times2500}$

T=1.566 N.m is the torque applied by the each piston of the engine.

Determine the stopping location of the prize wheel. At this moment it is centered on the number 11. It is spinning at a rate of

Goshia [24]

Answer:

The wheel spins for 11.43s. The number cannot be determined.

Explanation:

We know that initial velocity is 124.4 rpm = 13.027137522 rad/s, acceleration is -1.14 rad/s^2, and final velocity is assumed to be 0 rad/s. We are asked to find t and displacement. We use the equation $\omega=\omega_0+\alpha t$ where $\omega=0 rad/s$ , $\omega_0=13.027 rad/s$ , $\alpha=-1.14rad/s^2$ , and $t=?$ .

Rearrange the equation to obtain $\frac{\omega-\omega_0}{\alpha}=t$ . Plug in the numbers and solve to obtain $t=11.43s$ .

The number of the wheel cannot be determined as we do not know the placement of numbers on the wheel.

A skier with a 65kg mass skies down a 30 degree incline hill. The coefficient of friction is 0.1. a. Draw a free body diagram. b

djyliett [7]

B is the answer! Because no one would be pushing the rock all the way down the hill it would just go down by itself by rolling!!

Hope i helped plz mark as brainlist and 5 star'!
