Answer:
The first case requires more force to spin de bucket.
Explanation:
As we know, the centripetal force is directly proportional to the mass, the equation is given by:
The first case has a quarter more water than the second case, therefore the first case requires more force to spin de bucket.

In an uniformly accelerated motion, the velocity of the object follows the law:
where
is the initial velocity, a the acceleration and t the time.
In our problem, the robot starts from rest, so the initial speed is zero:
. The robot is in free fall, so the acceleraion is the gravitational acceleration
. therefore, after a time
, the velocity is
12m/s
Explanation:
Given parameters:
Distance run by student = 120 meters
Time = 10 seconds
Unknown:
Speed = ?
Solution:
Speed is the rate of change of distance with time:
Speed = 
Now input the parameters:
Speed = 
= 12m/s

A chemical process with an e-factor of 1 creates less waste than an e-factor of 25 is True.
<h3>What do you mean by E-factor?</h3>
The actual amount of waste produced during the process—which is referred to as anything other than the targeted product—is known as the E factor. It considers the chemical yield as well as reagents, solvent losses, all process aids, and, in theory, fuel (although this is often difficult to quantify). There is one exception: I often did not include water in the E factor calculation. For instance, only the inorganic salts and organic chemicals present in an aqueous waste stream are taken into account; the water itself is left out. In many instances, the inclusion of water used in the process might result in very high E factors, which can make it challenging to compare processes in a meaningful way.

Answer:
887.1Hz
Explanation:
Given parameters:
Speed of sound wave = 330m/s
Wavelength = 0.372m
Unknown:
Frequency = ?
Solution:
To solve this problem, we use the expression below:
Speed = Frequency x wavelength
330 = Frequency x 0.372
Frequency = 887.1Hz
