Answer:
m/s^2
Explanation:
Force = mass × acceleration
kgm/s^2 = kg × acceleration
where acceleration = Force ÷ mass
= kg m/s^2 ÷ kg
:Acceleration = m/s^2
Before 7 after 9. A pH smaller than 7 indicates acidity with 0 being completely acidic. A pH greater than 7 shows alkalinity with 14 being completely alkaline. 7 is neutral. Since NaOH is alkaline, adding it to a neutral substance would increase the pH and it would increase from 7 to 9.
Answer: 24.24 m
Explanation:
A player throws football 50.0 m at 61° North of west. we will write this in terms of horizontal and vertical components.
Horizontal component: 50 cos 61° = 24.24 m which is westwards
Vertical component: 50 sin 61° = 43.73 m which towards North.
Refer to diagram below.
Thus, the westward component of displacement of the football is the horizontal component of the displacement = 24.24 m.
Answer:
I think the answer is As you increase the current the resistance increases too.
Answer: Two glass marbles bounce off each other.
Explanation:Elastic collisions are collisions in which both momentum and kinetic energy are conserved. The total system kinetic energy before the collision equals the total system kinetic energy after the collision. If total kinetic energy is not conserved, then the collision is referred to as an inelastic collision.
An elastic collision occurs when the two objects "bounce" apart when they collide. Two rubber balls are a good example. In an elastic collision, both momentum and kinetic energy are conserved. Almost no energy is lost to sound, heat, or deformation.
