Answer:
<em>physical quantities that cannot be defined in terms of other quantities.</em>
<em>Examples</em><em>:</em><em> </em><em>Length - meter (m)Time - second (s)Amount of substance - mole (mole)Electric current - ampere (A)Temperature - kelvin (K)Luminous intensity - candela (cd)Mass - kilogram (kg)</em>
Answer: part 1 is mass and part 2 is density
Explanation: I just did it and got it right
The resistance would increase.
The answer would be energy, because all wave emitters give off at least one type of energy....
Answer:
0.528m
Explanation:
a)58.7 cm = 0.587 m
Let g = 9.8m/s2. When the frog jumps from ground to the highest point its kinetic energy is converted to potential energy:


where m is the frog mass and h is the vertical distance traveled, v is the frog velocity at take-off


b) Vertical and horizontal components of the velocity are


The time it takes for the vertical speed to reach 0 (highest point) under gravitational acceleration g = -9.8m/s2 is

This is also the time it takes to travel horizontally, we can multiply this with the horizontal speed to get the horizontal distance it travels
