Answer:
1419.01436 N
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
The force on the car
Magnitude of the horizontal net force that is required to bring the car to a halt is 1419.01436 N
Answer:
I think 18 not entirely sure though
Explanation:
Group 18 are the noble group so 16 + 2 = 18
The weight of the plane is (mass) x (acceleration of gravity).
Neither of these changes when the plane rises from the ground.
Its weight on the ground is equal to (the same as) its weight in the air.
Hydrogen is written as H2 and oxygen is written as O2
When they bond it is a covalent bond.
Hydrogen has 1 negative electron , which would attract one from oxygen, so its outer shell would have 2 electrons.
Oxygen outer shell holds 8 electrons.
The answer is
2 and 8
Answer:
An object at rest does not move and an object in motion does not change its velocity, unless an external force acts upon it
Explanation:
This statement is also known as Newton's first law, or law of inertia.
It states that the state of motion of an object can be changed only if there is an external force (different from zero) acting on it: therefore
- If an object is at rest, it will remain at rest if there is no force acting on it
- If an object is moving, it will continue moving at constant velocity if there is no force acting on it
This phenomenon can be also understood by looking at Newton's second law:
F = ma
where
F is the net force on an object
m is the mass
a is the acceleration
If the net force is zero, F = 0, the acceleration of the object is also zero, a = 0: therefore, the velocity of the object does not change, and it will continue moving at the same velocity (which can be zero, if the object was at rest).
