Answer:
yes. everything around you is matter including you!
Heyy! :) I'm Jenna, and Im here to help you on your Math problem!
It says that he/she bought 2 $27 bingo games so thats 27 times 2 which equals:
54
The therapist has 12 puzzles at $5 each so thats 5 times 12 which equals:
60
The therapist has 14 Jars of Paint at $7 each so that 14 x 7 which equals:
98
The therapist has 20 paint brushes at $2 each so thats 20 x 2 which equals
40
and 24 packages of construction paper at $7 each so thats 24 x 7 which equals:
168
To get the final answer of how much money he spent, you'll have to add all of the numbers together.
Answer:
420
Answer:
B. twice as much kinetic energy
Explanation:
Lets take the mass of the first marble =2 m
the mass of the second marble = m
We know that velocity of particle does not depends on their mass that is the velocity of both mass will be same after dropping from the roof.
We know that kinetic energy of a mass is given as
Kinetic energy for heavier mass
Kinetic energy for light mass
KE=2 KE '
Form above two equation we can say that ,the kinetic energy for the heavier mass is twice the lighter mass.
Therefore the answer will be B.
If it is stationary, its not moving. there is no movement
Answer:
v' = 0.714 m/s
Explanation:
Solution:
- Assuming no external torque is acting on the system then the angular momentum is conserved for the system.
- The initial momentum angular Mi and final angular momentum Mf are as follows:
Mi = Mf
m*L*v = m*x*L*v'
Where,
m : mass of the telescope
L : Length of teether line
v: Initial speed
v' : Changed speed.
- Then we have:
L*v = x*L*v'
v' = v / x
v' = 2 / 2.8
v' = 0.714 m/s
