Answer:
the statement is true
Explanation:
The bonds in the molecules give rise to irrational energy levels, are quantized, that is, they are discrete
In order for a photon to create a transition between the given levels it has to have the same energy as these two levels, it is in this case if the photon has the energy of the bond can be promised to the electron and be absorbed.
In summary the statement is true
Answer:
It will be 0 newton
Explanation:
Basic concept to understand here is the increase and decrease in apparent weight of a body when elevator moves upward and downward. Remember, the mass does not change but apparent weight changes with the motion of elevator. It is due to the push by floor. Simply, if you standing on earth, the gravity pulls you down, but ground push you up, so both forces balance each other and you stand straight.
Notice that when elevator moves upwards, the apparent weight of a person increases which is due to the inertia and push of floor, our body resists to move upward so floor push us harder and we feel more weight.
Similar is the case for downward motion, when lift moves downward, our body which is at rest but its weight is acting downward. So, floor push us less harder against our original weight. So our apparent weight reduces.
Now in case of cable break, Lift will start to go along acceleration, there will be no floor and we would be like on the space, so their would be no apparent weight and weighing scale would show our weight 0
Answer:
123 km/h
Explanation:
The distance between the Jeep Wrangler and the Ford Taurus is increasing.
Let us consider the north direction as positive when observing from the ground
So, the south direction will be negative
But when the observer is one of the cars the direction will be the same i.e., moving away from each other, so the velocity will be added.
Hence velocity of the Jeep relative to the Ford will be
Velocity of the Jeep + Velocity of the Ford
= 74+49 = 123 km/h
∴ Velocity of the Jeep relative to an observer in the Ford is 123 km/h
Answer:
Explanation:
1.)
2.) COP
3.) Rate of heat absorption
COP
Therefore, cooling in minutes=
COP cannot cycle=
Rate of heat absorption
cooling time in minutes with cannot cycle
