Answer:
The height at which the object is moved is 10 meters.
Explanation:
Given that,
Force acting on the object, W = F = 490 N
The gravitational potential energy, P = 4900 J
We need to find the height at which the object is moved. We know that the gravitational potential energy is possessed due to its position. It is given by :
So, the height at which the object is moved is 10 meters. Hence, this is the required solution.
Accelerating from rest at the rate of 7 m/s^2 for 3.9 s ...
D= 1/2 a t^2
D= (3.5) (3.9)^2
D= 53.2 m
The car travels 53.2 meters in space, and 3.9 seconds in tme.
Since the sound you hear from the siren has a HIGHER frequency
than the sound actually coming out of the siren, you know ... from
your knowledge of the Doppler effect ... that the distance between
you and the ambulance is decreasing.
Just from the sound alone, you can't tell whether it's the ambulance
moving toward you, or you moving toward the ambulance. Either
motion would produce the same effect, because the distance between
is decreasing. You'd need to find some other way to tell which one is
producing the motion. (at least MOST of it)
Answer:
a.movement
Explanation:
Electricity is defined a set of natural phenomena associated with static charges or the movement of electric charges. Whenever we are talking about electricity, we are usually referring to the transport of energy when electric charges move; therefore, whenever, there is movement of charges, there is electricity.
So, it is correct to say that electricity is the movement of charged particles.
Electricity is NOT a collection of charged particles (choice b), because stationery charges do not transport energy when left untouched; some energy transfer has to happen if we are to use the word 'electricity'.
In a similar fashion, electricity is also NOT a build up of charged particles (choice c). Although charge build up does take energy, and charges are moving, but that happens in the domain of the definition of electricity—charge build up by itself is not a definition of electricity.
Storm weather likely happens in the town when the air masses meet because of difference of temperature and humidity of both air masses.
<h3>What weather happens when air masses meet?</h3>
When air masses move by wind, they carry different weather conditions from the weather conditions of other region. This difference in weather conditions can create a severe storm.
So we can conclude that Storm weather likely happens in the town when the air masses meet because of difference of temperature and humidity of both air masses.
