Scientists must have an unbiased type of investigation. These type of science requires three major characteristics for it to be functional and sticked to the truth: they must be impartial, accuarate and truthful. Without these characteristics there is no way forensic science must be treated as science.
If a cell grows beyond a certain size, materials will not be able to pass through the membrane fast enough to accommodate the inside of the cell. So when the cell reaches a size too large, it will divide into smaller cells in order to maintain a surface are/volume ratio that is more favorable to the functioning of the cell. Therefore, cells remain small in order to survive.
Answer:371.564 mi
Explanation:
Given
Airplane flies northwest for 250 mi and then travels west 150 mi
That is first it travels 250cos45 in - ve x direction and simultaneously 250sin45 in y direction
after that it travels 150 mi in -ve x direction
So its position vector is given by
so magnitude of displacement is
|r|=371.564 mi
<span>d = 950 m - 4.9t^2 m
The distance an object moves under constant acceleration is
d = 0.5at^2
where
d = distance
a = acceleration
t = time.
Since we're falling and since we're starting at 950 m above ground, the formula becomes:
d = 950 m - 0.5at^2
Substituting known values, and simplifying gives us
d = 950 m - 0.5*9.8 m/s^2 * t^2
d = 950 m - 4.9 m/s^2 * t^2
Since time is in seconds, we can cancel out the seconds in the units, getting
d = 950 m - 4.9t^2 m</span>
First object:
m=10 kg
F=20 N
F=ma, then:
a=F/m
a=20/10=2 m/s²
Second object:
m=18 kg
F=30 N
a=F/m
a=30/18=1.6 m/s²
The first object has a higher acceleration.
