Hi there!

The next thing that alcohol affects is <span>B. basic muscle control. The reason for this is that alcohol is what is called a "depressant" which means it relaxes the body and mind during the euphoria.

Boyle's law balloon was filled to a volume of 2.50 l when the temperature was 30.0∘

aliina [53]

To solve this we assume that the gas inside the balloon is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant pressure and number of moles of the gas the ratio T/V is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

T1 / V1 = T2 / V2

V2 = T2 x V1 / T1

V2 =284.15 x 2.50 / 303.15

Consider the model above. It represents the electrical force. As r increases, the attractive force decreases. How would this mod

aivan3 [116]

Answer:

As we keep on increasing the radius the value of the gravitation force of attraction decreases and as we decrease the radius the gravitation force increases.

Explanation:

Like the coulombs law of electrostatics, the law of gravitation also depends inversely on the square of the value of r. Therefore, as we keep on increasing the value of r the value of the gravitation force decreases and as we decrease the value of the r the value of gravitation force increases.

Gravitation Force= $\frac{Gm_{1}m_{2} }{r^{2}}$

Coulombs's Law= $\frac{Kq_{1}q_{2} }{r^{2}}$

A proton moving in the positive x direction with a speed of 8.9 105 m/s experiences zero magnetic force. When it moves in the po

solniwko [45]

Answer:

The magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.

Explanation:

Given that,

Speed of a proton, $v=8.9\times 10^5\ m/s$ (due +x direction)

When it moves in the positive y direction it experiences a force of, $F=1.7\times 10^{-13}\ N$ (due positive z direction)

We need to find the magnitude and direction of the magnetic field. The magnetic force is given by :

$F=q(v\times B)\\\\B=\dfrac{F}{qv}\\\\B=\dfrac{1.7\times 10^{-13}}{1.6\times 10^{-19}\times 8.9\times 10^5}\\\\B=1.19\ T$

For direction :

$F=q(v\times B)\\\\k=(+q)(j\times B)\\\\B=-i$

So, the magnitude of magnetic field is 1.19 T and its direction magnetic is in negative x direction.

A batter hits a pitched ball when the center of the ball is 1.22 m above the ground. The ball leaves the bat at an angle of 45°

Sveta_85 [38]

Answer:

2.56m

Explanation:

This is problem 4.47 from your textbook.

Find: Whether a batted baseball clears a fence, and by what amount it does or does not.

Given: The baseball’s initial launch height and angle, the range the baseball would have without the fence, the distance to the fence and its height.

Let the y axis run vertically and the x axis horizontally. Let the range the baseball would have without the fence be R=107 m, with the distance to the fence d=97.5m and its height hfence=7.32 m. The baseball is batted at an angle θ=45° at speed vi a height of hbat=1.22m above the ground.

Let the origin be at the position the ball leaves the bat. The height of the fence relative to the height of the bat is then

δh = hfence − hbat

What we really need to determine is the ball’s y coordinate at x = d. If y > δh, the ball clears the fence. We can use the range the baseball would have without the fence and the launch angle to find the ball’s speed, which will allow a complete calculation of the trajectory.

Relevant equations: We need only the equations for the range and trajectory of a projectile over level ground:

R = (vi*sin2θ)/g

For convenience sake and easy reading, I extracted the solution of your textbook for the remaining parts of the solution.

Hence, it is seen that the ball does clear the fence, by approximately 2.56 m
