Answer:
Only if that object is being moved while carried
Explanation:
Work = Force • distance travelled
While holding an object would need force equal to that objects mass multiplied by 9.8, if it hasn't moved, then no work is done.
if you were to carry the object and have it travel some distance, then work would be done on that object.
Answer: D. the distance between the highest points of consecutive waves
Explanation:
The wavelength of a wave is defined as the <em>distance traveled by a periodic perturbation that propagates through a medium in a given time interval</em>. It is usually represented by 
and can be calculated if the frequency of the wave is known, since there is an inverse relationship between both.
In the specific case of a periodic sine wave (which is the way in which a wave is usually represented graphically) the wavelength can be determined as the distance between two consecutive maxima of the disturbance.
Therefore, the correct option is D.
<u>Rated </u>
A t-rated switch may be used to (its/a) <u>Rated</u> current capacity current capacity when controlling an incandescent lighting load.
<h3>What is "current rating"?</h3>
- The greatest current that a fuse is rated to carry for an infinite duration without significantly degrading the fuse element is known as the current rating.
- There is also a large selection of power switching transistors that have voltage ratings well over 1000V and current ratings up to several hundred amps.
<h3>What does the term "rated current" mean?</h3>
- When an electrical device receives its rated voltage and outputs its rated power, it flows at its rated current.
- So, when a device is designed for a certain amperage, that amperage is referred to as the equipment's rated current.
<h3>What does electrical "rated" mean?</h3>
- An electrical appliance's rating reveals the voltage range at which it is intended to operate as well as the current consumption at that range.
- These numbers are typically shown on a rating plate that is fastened to the device, such as 230 volts, 3 amps.

Answer:
The speed of the center of mass of the two carts is 0.103 m/s
Explanation:
It is given that,
Mass of the air track cart, m₁ = 350 g = 0.35 kg
Velocity of air track cart, v₁ = 1.25 m/s
Mass of cart, m₂ = 280 g = 0.28 kg
Velocity of cart, v₂ = -1.33 m/s (it is travelling in opposite direction)
We need to find the speed of the center of mass of the two carts. It is given by the following relation as :
Hence, this is the required solution.
Answer:
The buoyant force is a result of pressure exerted by the fluid. The fluid pushes on all sides of an immersed object, but as pressure increases with depth, the push is stronger on the bottom surface of the object than in the top
