Henrietta is going off to her physics class, jogging down the sidewalk at a speed of 2.70 m/s. Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 36.5 m above the street level and directly above the sidewalk, to throw them to her. Bruce throws them horizontally at a time 4.00 s after Henrietta has passed below the window, and she catches them on the run. You can ignore air resistance. Wit what initial speed must Bruce throw the bagels so Henrietta can catch them just before they hit the ground? Where is Henrietta when she catches the bagels?
Answers
Answer:
The velocity is
Henrietta is at distance from the under the window
Explanation:
From the question we are told that
The speed of Henrietta is
The height of the window from the ground is
Generally the time taken for the lunch to reach the ground assuming it fell directly under the window is
=>
=>
Generally the time taken for the lunch to reach Henrietta is mathematically represented as
Here is the time duration that elapsed after Henrietta has passed below the window the value is given as 4 s
Now
=>
Generally the distance covered by Henrietta before catching her lunch is
=>
=>
Generally the speed with which Bruce threw her lunch is mathematically represented as

Answer:
Speed
Explanation:
If a vehicle hit any other object then its speed will slow down or some time the vehicle will stop its depends on the force exerted by other object on the vehicle.
The change in speed of vehicle is due to momentum because momentum is always conserved. So to conserve the momentum the speed of the vehicle decreases because after hitting the overall mass is increases.

A trough with an amplitude of 1 will form.
A crest with an amplitude of 9 will form.
A trough with an amplitude of 9 will form.
Answers
Answer: A crest with an amplitude of 9 will form.
Explanation:
From super position principle, we know that when two waves move in same medium meet, then the net amplitude of the super imposed waves is sum of amplitudes of individual waves.
A constructive superposition takes place when crest meets crest and crest is formed of higher amplitude or trough meets trough and forms trough of higher amplitude. A destructive superposition takes place when crest of one meets trough of other -a crest or trough can form depending on the larger amplitude of either.
In the given situation, crest of wave X meets crest of wave Y. The amplitude of the super imposed wave would be = 5 + 4 = 9 and a crest would form.

Answer:
In a radio or television, the instrument that converts electrical energy into sound signals or image signals is called a transducer. Transducers are devices that can convert one form of energy into another.
In the context of television, a television camera is an example of a transducer that converts light energy (captured through a lens) into electrical signals representing images or video. These electrical signals can then be processed and transmitted for display on a television screen.
In the context of a radio, a microphone is an example of a transducer that converts sound waves (acoustic energy) into electrical signals. These electrical signals, which represent sound, can then be amplified, modulated, and broadcast over the radio waves for reception by a radio receiver.
So, depending on whether you're referring to a television or a radio, the specific transducer used for converting electrical energy to sound or image signals may vary, but the concept of a transducer applies to both.

Disequilibrium occurs when the quantity of supply does not equal the quantity of demand.
The market is experiencing a disequilibrium when the market price is above or below the equilibrium price. Whenever markets experience imbalances—it creates disequilibrium prices, surpluses, and shortages—market forces drive prices toward equilibrium.
A surplus exists when the price is above equilibrium, which encourages sellers to lower their prices to eliminate the surplus.
A shortage will exist at any price below equilibrium, which leads to the price of the good increasing.
For example, imagine the price of dragon repellent is currently $6 per can. People only want to buy 400 cans of dragon repellent, but the sellers are willing to sell 600 cans at that price. This creates a surplus because there are unsold units. Sellers will lower their prices to attract buyers for their unsold cans of dragon repellant.
