Let both the balls have the same mass equals to m.
Let
and
be the speed of the ball1 and the ball2 respectively, such that
![v_1>v_2\;\cdots(i)](https://tex.z-dn.net/?f=v_1%3Ev_2%5C%3B%5Ccdots%28i%29)
Assuming that both the balls are at the same level with respect to the ground, so let h be the height from the ground.
The total energy of ball1= Kinetic energy of ball1 + Potential energy of ball1. The Kinetic energy of any object moving with speed,
, is ![\frac 12 m v^2](https://tex.z-dn.net/?f=%5Cfrac%2012%20m%20v%5E2)
and the potential energy is due to the change in height is
[where
is the acceleration due to gravity]
So, the total energy of ball1,
![=\frac 12 m v_1^2 + mgh\;\cdots(ii)](https://tex.z-dn.net/?f=%3D%5Cfrac%2012%20m%20v_1%5E2%20%2B%20mgh%5C%3B%5Ccdots%28ii%29)
and the total energy of ball1,
.
Here, the potential energy for both the balls are the same, but the kinetic energy of the ball1 is higher the ball2 as the ball1 have the higher speed, refer equation (i)
So, ![\frac 12 m v_1^2 >\frac 12 m v_2^2](https://tex.z-dn.net/?f=%5Cfrac%2012%20m%20v_1%5E2%20%3E%5Cfrac%2012%20m%20v_2%5E2)
Now, from equations (ii) and (iii)
The total energy of ball1 hi higher than the total energy of ball2.
Answer:
Industries outlook is uncertain
Explanation:
Competitive pressures stemming from the threat of entry are stronger when the industry's outlook is uncertain or highly risky, entry barriers are low, and very few existing industry members are looking to expand their market reach by entering product segments or geographic areas where they currently do not have a presence. entry barriers are low, the pool of entry candidates is large, and existing industry members are earning good profits. there are fewer than 10 entry candidates with the potential to hurdle the industry's barriers to entry. t is difficult or costly for a customer to switch to a new brand, the total dollar investment needed to enter the market successfully exceeds $5 million, and existing governmental regulations impose significant cost and compliance burdens on industry members. buyers have strong brand preferences and high degrees of loyalty to their preferred brand and when it takes new entrants less than 5 years to secure attractive amounts of space on retailers' shelves and build a well-recognized brand name.
Answer:
Disagree
Explanation:
We cannot see infared lights.
Answer:
120s^-1
Explanation:
v=12v
I=10A
and since rate is with time, therefore rate=energy/time.
H=IV
10×12=120/s
therefore the rate is 120s^-1
