Answer:
50 Mph.
Explanation:
According to the National Severe Storms Laboratory, winds can really begin to cause damage when they reach <em><u>50 mph</u></em>. But here’s what happens before and after they reach that threshold, according to the Beaufort Wind Scale (showing estimated wind speeds): - at 19 to 24 mph, smaller trees begin to sway.
Explanation:
Because combining primary colors od light like red, blue, and green created secondary colors like yellow, cyan, and magenta
Explanation:
A chemical reaction in which heat or energy is released is known as an exothermic reaction.
On the other hand, when two objects are placed together and heat flows from hotter object to colder object then this process is known as conduction. Therefore, energy is dissipated in conduction process.
Since energy released released goes into the atmosphere and is not used anywhere.
Thus, we can conclude that when an exothermic reaction releases thermal energy, this energy is usually not useable to do work and it is dissipated by conduction.
During the diving when a diver jumps off from platform he brings her knees and arms closer to the body
This is because when diver is in air he don't have any torque about his center of mass which shows that angular momentum of his body will remain constant during his motion in air
Now we can say product of his moment of inertia and his angular speed will remain constant always
So here if we decrease the moment of inertia of the body during our motion then angular speed will increase so that product will remain constant
and this is what the diver use during his diving
so correct answer will be
<u><em>It decreases her moment of inertia.</em></u>
Answer: Correct answer is B = 1.776933×
Explanation:
Given :
Moment of inertia I = 8.26×
kg
Mass of planet m = 6.54×
kg
Also, Planet is solid sphere so that, Moment of inertia is I =
m
=0.4m
Where R is radius of planet
Putting into calculation
We get,
I =
m
8.26×
= 0.4×6.54×
×
8.26×
= 2.616 
3.15749235×
= 
R = 1.776933×
Thus, Correct answer is B = 1.776933×
