Answer:
0.47922 kgm/s and will move right to left
Explanation:
= Mass of broccoli-tomato-pickle-onion-mushroom pizza = 235 g
= Mass of veggieburger-on-a-bun = 351 g
= Velocity of broccoli-tomato-pickle-onion-mushroom pizza = 1.65 m/s
= Velocty of veggieburger-on-a-bun = -2.47 m/s
Left to right is considered positive direction and the opposite is negative direction
Net momentum is

The combined dish has a momentum of 0.47922 kgm/s and will move right to left
Answer:


Explanation:
(a)
Given:
- mass of comet,

- velocity of the comet,

<u>Now, the kinetic energy of the comet can be given by:</u>



(b)
Given:
- energy released by 1 megaton of TNT,

<u>Now the kinetic energy of the comet in terms of energy of 1 megaton TNT:</u>

i.e.

Explanation:
1) Radar uses radio waves, which are a type of electromagnetic energy. Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects. Sound waves are a type of acoustic energy. Because of the different type of energy used in radar and sonar, each has its own applications.
2)Radar systems operate using radio waves primarily in air, while sonar systems operate using sound waves primarily in water (Minkoff, 1991). Despite the difference in medium, similarities in the principles of radar and sonar can frequently result in technological convergence.
Momentum of car
Given: Mass m= 1,400 Kg; V = 6.0 m/s
Formula: P = mv
P = (1,400 Kg)(6.0 m/s)
P = 8,400 Kg.m/s
Velocity of the rider to have the same momentum as a car.
Mass of rider and bicycle m = 100 Kg
P = mv
V = P/m
V = 8,400 Kg.m/s/100 Kg
V = 84 m/s
That is the Sigma Symbol. It’s the addition of a sequence of numbers; the result is the sum of the total. if numbers are added sequentially from left to right, any intermediate result is a partial sum, prefix sum, or running total of the summation
