Answer:
9.66 x 10^-6 m
Explanation:
Use the Wein's displacement law
Where, b is the Wein's constant
b = 2.898 x 10^-3 meter-kelvin
So, λm x 300 = 2.898 x 10^-3
λm = 9.66 x 10^-6 m
The work done is 8427 J while the energy expended is 80.25 W.
<h3>What is work done?</h3>
Work done is defined as the product of the force and the distance. We know that the work done in a gravitational field is given as;
W = mgh
Total mass of the water bucket and chain = 13.9 kg + 19.3 kg = 33.2Kg
Distance covered = 25.9 m
W = 33.2Kg * 9.8 m/s^2 * 25.9 m
W = 8427 J
Recall that the work done = Energy expended
Power = Energy expended/ Time
Power = 8427 J/ 1.75 * 60 seconds
Power = 80.25 W

if they are oriented in the shape of an equaliteral triangle
basically the angle between them is 120 degrees if they both start at the same point
The momentum of daemon and his cart as he rolls immediately after they are no longer in contact 81.69kgm/s.
<h3>What is momentum ?</h3>
In Newtonian physics, an object's linear momentum, translational momentum, or simply momentum is defined as the product of its mass and velocity. It has both a magnitude and a direction, making it a vector quantity. If an object has mass m and velocity v, then its momentum p is given by
p = mv
Therefore, the Newton-second may be used as the unit for momentum (Ns). In the CGS system, the unit of momentum is the gram-centimeters per second (gcm/s), where the mass is measured in grams and the velocity in centimeters per second.
Total momentum of the system = momentum of christine's cart + momentum of daemon's carttotal momentum of the system
= 37.8 kgm/s + 43.89kgm/s
= 81.69kgm/s.
