The arrow in chemical equation means 'turns into' i think
Answer:Twice
Explanation:
It is given that car is raised on a lift with respect to ground.
Suppose car is raised by a height of h m from ground having mass m so gain in Potential Energy by car is
Gain in 
Now if it were raised twice as high,i.e. 2 h height from ground then gain in Gravitational Potential Energy


It is clear that 
Thus in second case gain in Potential Energy is twice as compared to first case
1) G
2) E
3) D
4) I
5) J
6) C
7) H
8) F
9) B
10) A
I think... i am not 100% sure....
Answer:
from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection, and radiation. Sometimes more than one may occur at the same time.
Explanation:
Answer:
540m/s
Explanation:
Given parameters:
Frequency of the wave = 18000Hz
Wavelength of the wave = 0.03m
Unknown:
How fast is the wave traveling = ?
Solution:
How fast the wave is traveling is a measure of the speed of the wave;
Speed of wave = frequency x wavelength
Now insert the given parameters and solve;
Speed of wave = 18000 x 0.03 = 540m/s
