To solve this problem it is necessary to apply the concepts related to the kinematic equations of motion for which the height of a particle is defined as a function of gravity as,

Where,
h = Height
g = Gravity constant
v = Velocity
There is not change in the horizontal component, therefore there is only the component horizontal given (18m/s) and the vertical component:



Applying the vector theory to find the magnitude of a vector we have to


The speed at which the ball was thrown was 25.38
Answer:
True
Explanation:
In Massachusetts it's illegal to drive while texting or on your phone.
Answer:

Explanation:
The index of refraction is equal to the speed of light c in vacuum divided by its speed v in a substance, or
. For our case we want to use
, which for our values is equal to:

Which we will express with 3 significant figures (since a product or quotient must contain the same number of significant figures as the measurement with the <em>least</em> number of significant figures):

<span>So we want to know what is the direct effect of the gas particles if the force of their collision with the walls of the container is increased. Pressure, microscopically, is defined as the number of collisions per unit area. If we increase the force of the collision, the pressure increases so that is the direct effect. </span>
