Average speed = (distance covered) / (time to cover the distance)
= (200 miles) / (5.5 hours)
= (200/5.5) mile/hour
= 36.4 miles per hour (rounded)
Answer:
Kinematics is the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.
-the features or properties of motion in an object.
Explanation:
Hope this helps <3
Have a great day!
Answer:

Explanation:
Formula for AVERAGE acceleration

is Final Velocity
is Initial Velocity
is Final Time
is Initial Time
Most of the time, the initial time will be 0, so you won't have to subtract.
Well,
For the first one, the answer would be C, because all organisms in Kingdom Animalia must eat in order to survive.
For the second one, all of the options are in Kingdom Animalia, but worms (A) and clams (C) are invertebrates. So that leaves options B and D.
Answer:
50 N
Explanation:
Since the refrigerator doesn’t move, that means the force of friction equals the amount of force the child exerts on the fridge. If the friction force were greater than the force by the child, the fridge would start accelerating towards the child. If it were less than the force the child exerted, the fridge would start accelerating away from the child. Therefore, the net force must be 0, in this case, the friction force is equal to the force the child exerted, for it to stay at rest (as Newton’s First Law stated).
I hope this helps! :)
