Answer:Kg•m/s
Explanation:the SI unit for momentum is kg•m/s
Momentum=mass x velocity
Unit for mass=kg
Unit for velocity=m/s
Therefore they unit for momentum is kg•m/s
Answer:
P = 30000 [kg*m/s]
Explanation:
Momentum in physics is defined as the product of force in the given time interval. In this way, it can be expressed by means of the following equation.
where:
P = momentum [kg*m/s]
F = force = 6*10⁴ [N]
t = 0.5 [s]
Now replacing:
![P=6*10^{4}*0.5\\P=30000[kg*m/s]](https://tex.z-dn.net/?f=P%3D6%2A10%5E%7B4%7D%2A0.5%5C%5CP%3D30000%5Bkg%2Am%2Fs%5D)
Answer:
If an object pushes out an amount of water equal to its own weight, the upward force acting on it will be equal to gravity - and the object will float.
Explanation:
The buoyant force has an impact on the object in the water and equals the weight of the water displaced by the object. Every object placed in water has some buoyancy force that pushes it against the gravitational force, and this means that any object loses weight in the water.
Use the formular d = v x t
d = 2m
v= 100m/s
t= d / v
= 2 / 100
= 0.02sec
Answer:
The pole stores elastic potential energy when the pole is bent because its shape is change from its natural shape and it will want to go back to its original form, just like a spring or stretched elastic material.
