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.
Answer:
This is one of the hottest summers America has ever seen and Jeremiah Warren is taking advantage of the heat wave and doing a little cooking…in his car!
It was about 98 or 99 degrees in Texas, so Jeremiah thought he’d head outside to see if it was hot enough to actually cook food. He buttered up a frying pan on his dashboard and filled it with an egg, cookie dough, a hot dog and bacon (mmm…bacon!). He set up another frying pan on the sidewalk and a few hours later he came back for a mid-day snack.
Explanation:
ON EARTH, every kilogram of mass weighs about 2.205 pounds.
So if you know the weight (in pounds), and you know that it was
weighed on Earth, you can simply divide the pounds by 2.205 ,
and you'll get the mass (in kilograms).
I can see that on this science homework, they used 2.2 for the weight
of 1 kilogram expressed in pounds. So just divide the weight by 2.2
to get the mass in kilograms.
(The weight number they gave you is not so random. :-) )
Answer:
New pressure group is N
Explanation:
The Repetitive Dive table has to be checked, the residual nitrogen for the maximum depth of 38 feet as a "D" diver, then add that to the actual dive time to get the total nitrogen time. The total nitrogen time and the maximum depth of 38 feet would put you on a pressure group N.
Answer:
what do you mean by that.
