Answer:
weight = 25*10 =250 N
Explanation:
g must be given in units of m/s^2
The weight of any type of body will be the product of his mass by the gravity
where:
m =mass [kg]
F = force [N] or [kg*m/s^2]
g = acceleration [m/s^2]
Answer:
A) The net force
Explanation:
If two forces of equal strength act on an object in opposite directions, the forces will cancel, resulting in a net force of zero and no movement.
In a collision, there is a force on both objects that causes an acceleration of both objects; the forces are equal in magnitude and opposite in direction. For collisions between equal-mass objects, each object experiences the same acceleration.
Answer:
B: air pressure inside the car drops suddenly
Explanation:
Air in the car drops suddenly because the roof region has lowered pressure than the atmospheric pressure usually varying with the speed of the car
Answers
1.) non-polar
2.) non-polar
3.) Polar
4.) Polar
Non-polar molecules are essentially molecules that have an even distribution of of electrical charges.
Polar molecules is the separation of electric charges, having one positive end and another negative end.
