Answer:
Lion Average speed:60 km/h
Explanation:
Answer:
the final velocity of the wagon is 6 m/s.
Explanation:
Given;
initial velocity of the wagon, u = 4 m/s
mass of the wagon, m = 35 kg
energy applied to the wagon, E = 350 J
The final velocity of the wagon is calculated as;
E = ¹/₂m(v² - u²)
Therefore, the final velocity of the wagon is 6 m/s.
Answer:
Because work can be defined as force time distance, we can also use the following equation
Solution
P=power (w or ft-lbf/s)
F=force (N or lbf)
D=distance (m or ft)
T=time (sec)
One horsepower is equivalent to 550 ft-lbf/s and 745.7 watts.
<span>There are charges in a neutral atom. These
charges belong to electron and proton which is balanced inside the neutral
atom. But basically, neutral atoms do not have any charges because since the
number of protons (positively charged electron), and the number of neutrons
(negatively charged electrons or no charged at all) are balanced making the
charge equals to zero. </span>
