In order to get the propoerty of work you need to use the following formula
<span>work = force times distance
</span>replacing data you will get:
W = (1.500) (3)
W = 4.500 NM
The answer should be in NM. So it will be 4500 NM againts the force of gravity
Answer:
5.15348 Beats/s
4.55 mm
Explanation:
= Velocity of sound = 342 m/s
= Velocity of sound = 346 m/s
= First frequency = 440 Hz
Frequency is given by
Beat frequency is given by
Beat frequency is 5.15348 Hz
Wavelength is given by
Relation between length of the flute and wavelength is
At v = 346 m/s
Difference in length is
It extends to 4.55 mm
Answer:
(1) Offer the right benefits
(2) Be transparent and open
Explanation:
There are two key strategies for retaining step are discussed below:
(1) Offer the right benefits: Benefits and perks can play a very good role in keeping employees happy, healthy and engaged. But benefits can go far beyond paid sick leaves and health coverage.
The company can give some financial awards to the employees which can help in exceeding performance and by this employees will stay in the company for a long period. Nearly 9 out of 10 companies will provide incentives and bonuses to the employees in coming next five years, according to the CTA.
(2) Be transparent and open: Creating open communication between the management and employees will help in the growth of the company as well as make the office atmosphere good. By this employees can share the ideas with the management and by these meetings, the employees can share their problems with management frankly will help employees to stay in the company for a longer period.
Thermal expansion<span> is the tendency of matter to change in shape, area, and volume in response to a change in temperature, through </span>heat<span> transfer. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases.so this can result in.......heat</span>
Answer:
Explanation:
According to the Coulomb's law, the magnitude of the electrostatic force between two static point charges 
and , separated by a distance 
, is given by
where k is the Coulomb's constant.
Initially,
The negative sign is taken with force F because the force is attractive.
Therefore, the initial electrostatic force between the charges is given by
Now, the objects are then brought into contact, so the net charge is shared equally, and then they are returned to their initial positions.
The force is now repulsive, therefore, 
The new charges on the two objects are
The new force is given by
