Answer:
D
Explanation:
What it means to be an autotroph is that you make your own food and plants do that by photosynthesis to be a heterotroph is finding food from other sources like autotrophs or even other heterotrophs
Answer:
none of the above or screwdriver
A)Linear motion
If there is not net force on the car, then by the Newton Second Law, the acceleration is zero, and the only valid option for zero acceleration is A).
Answer:
+5300 kg m/s
Explanation:
In any type of collision, the total momentum is conserved. Therefore, we can just calculate the total momentum before the collision, and the final momentum will be equal to the initial one.
The total momentum before the collision is:
where
is the mass of the bus
is the mass of the car
is the initial velocity of the bus
is the initial velocity of the car
Substituting the numbers, we find
And since the total momentum is conserved, this is also the final momentum after the collision.
Answer:
a = 0.016 m/s^2
the airplane's acceleration is 0.016 m/s^2
Explanation:
Applying the equation of motion;
v^2 = u^2 + 2as ........1
Where;
v = final velocity = 47.5 m/s
u = initial velocity = 28.9 m/s
a = acceleration
s = displacement = 45300m
From equation 1, making a the subject of formula;
v^2 = u^2 + 2as
2as = v^2 - u^2
a = (v^2 - u^2)/2s
Substituting the given values;
a = (47.5^2 - 28.9^2)/(2×45300)
a = 0.015684768211 m/s^2
a = 0.016 m/s^2
the airplane's acceleration is 0.016 m/s^2
