Answer:
D
Explanation:
Cells are the smallest unit of organizaiton, followed by tissues, organs, organ systems, and then organisms themselves.
<span>Her center of mass will rise 3.7 meters.
First, let's calculate how long it takes to reach the peak. Just divide by the local gravitational acceleration, so
8.5 m / 9.8 m/s^2 = 0.867346939 s
And the distance a object under constant acceleration travels is
d = 0.5 A T^2
Substituting known values, gives
d = 0.5 9.8 m/s^2 (0.867346939 s)^2
d = 4.9 m/s^2 * 0.752290712 s^2
d = 3.68622449 m
Rounded to 2 significant figures gives 3.7 meters.
Note, that 3.7 meters is how much higher her center of mass will rise after leaving the trampoline. It does not specify how far above the trampoline the lowest part of her body will reach. For instance, she could be in an upright position upon leaving the trampoline with her feet about 1 meter below her center of mass. And during the accent, she could tuck, roll, or otherwise change her orientation so she's horizontal at her peak altitude and the lowest part of her body being a decimeter or so below her center of mass. So it would look like she jumped almost a meter higher than 3.7 meters.</span>
Answer:
angular resolution = 0.07270° = 1.269 ×
rad
greatest distance from the camera = 118.20 m = 0.118 km
Explanation:
given data
diameter = 0.50 mm = 0.5 ×
m
distance apart = 15 cm = 15×
m
wavelength λ = 520 nm = 520 ×
m
to find out
angular resolution and greatest distance from the camera
solution
first we expression here angular resolution that is
sin θ =
.......................1
put here value λ is wavelength and d is diameter
we get
sin θ =
θ = 0.07270° = 1.269 ×
rad
and
distance from camera is calculate here as
θ =
.................2
I = 
I = 118.20 m = 0.118 km
Answer:
3km due West
Explanation:
Displacement is the distance traveled in a specific direction. From this definition, we can see that displacement is a vector quantity that has magnitude and direction.
So;
For the first day, the person walks 4km East:
4km
Start ----------------------------→ first day
7km
← ------------------------------------------------------ Second day
The displacement of the boy = 7km - 4km = 3km due West
