Answer:
1.9 s
Explanation:
We are given that
Length of cable=l=15 m
We have to find the time you have to move out of the way.
We know that
Time period,T=
Where g=
By using the formula
Time you have to move out
Hence,time you have to move out of the way=7.77 s
Answer: velocity = 50m/s
Distance moved=5m
Explanation:
Using the formula Ft=Mv i.e impulse= momentum
Where F= force ,t= time, M= mass, v = velocity
In this case we need to find v,
F,t,M are all given in the question.
Therefore, substituting the values we have
250N×0.1s=0.5kg×v. Mass=500g= 0.5kg
v=25/0.5= 50m/s
The distance the puck will move when it is on his stick.
D= Velocity × time
D=50m/s × 0.1s
D=5m
Goodluck...
Answer:
Every object has a different density and therefore carries different properties. When rays of white light strike an object, each ray light strikes the object with different frequency and therefore is absorbed and reflected differently from the host object.
In case if all the frequencies are absorbed by the object, it turns out to be black in color. Whereas on the other hand, if it is a mix of absorption and reflection, it makes different colors based on its frequencies and other properties of the object.
Answer:
however your doing it now?? ?? lol
The answer is enthalphy
Enthalphy especially used in thermodynamic system. It itncludes the internal energy which required to create the system and the ammount of energy required to establish its volume and pressure
Real life products of enthalphy applcation are refrigerator and compressor
Hope this help you out
