Life is unimaginable without all this, as it has become a necessity.
Explanation:
Answer:
The acceleration of the total mass decreases by half (1/2)
Explanation:
Given;
acceleration of sled = 2 m/s²
From Newton's second law of motion, F = ma
⇒m = F/a
F is the force applied by Jenny
This force applied by Jenny should be the same, after Tommy jumps on the sled, but the acceleration will change.
F = m₁a₁ = m₂a₂
Since m₂ = 2m₁, then we calculate a₂
m₁a₁ = 2m₁a₂
a₂ = a₁/2
Therefore,The acceleration of the total mass decreases by half.

18 - number of turns
19 - material of the fork
Explanation:
Answer: c Delta
Explanation:
A delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.
Hope this helps!!
