Answer:
So mass of the object will be 3.2 kg
Explanation:
We have net force on the object F = 16 N
Acceleration of the object
We have top find the mass of the object
From newton law of motion we know that force is given by
F = ma , here m is mass and a is acceleration
So
So mass of the object will be 3.2 kg
Answer:
- The diameter of the molecule of oil is
Explanation:
We define density as
So, the volume for our oil will be
the volume for a cylinder with radius r and height h is
So, we can obtain the height of the droplet of oil as:
the radius is
And this is the diameter of the oil molecule.
Answer: boy B, same
Explanation:
Given
One boy trips off the waterslide while the other starts sliding down
As there is no horizontal velocity, both boys have to travel the same vertical distance.
Their starting vertical velocity is zero and they need to travel the same vertical distance. Therefore, both boys splash water with the same velocity.
The time taken by boy B is more than boy A as boy B will travel some horizontal distance due to slide which will increase its time to reach the bottom.
Answer:
I think no.2 the answer
Because socialization and social resources are both for me
The advantage is that we do not run out of resources and a disadvantage is that is dangerous when a “human” gets too close and gets sick by the radiation.
