Answer:

3.0 seconds

Explanation:

We can solve the problem by considering the horizontal motion of the ball only. In fact, the ball moves by uniform motion (constant speed) along the horizontal direction, since there are no forces acting in this direction. The horizontal speed of the ball is given by:

v_x = v_0 cos \theta = (25 m/s)(cos 37^{\circ})=19.97 m/s

and it does not change during the motion.

We also know that the ball travels a horizontal distance of d = 60 m, so we can find the time it takes to cover the distance by using the equation:

t=\frac{d}{v}=\frac{60 m}{19.97 s}=3.0 s

Max will catch the ball \fbox{3\,{\text{s}}} after it was kicked by Maya.

Further Explanation:

The soccer ball kicked by Maya at a particular angle from the horizontal moves in the two-dimensional plane. It covers the distance in the vertical as well as in the horizontal direction.

As this motion of the soccer ball is a projectile motion, the vertical direction of motion of the ball is the motion under the action of acceleration due to gravity whereas the motion of the ball in the horizontal direction is the linear motion of the ball.

The velocity of the ball in the horizontal direction:

\fbox{\begin\\{v_x}=v\cos\,37^\circ\end{minispace}}

Here, {v_x} is the speed of the ball in the horizontal direction.

Substitute the value of v in above expression.

\begin{aligned}{v_x}&=\left({25\,{{\text{m}}\mathord{\left/{\vphantom{{\text{m}}{\text{s}}}}\right.\kern-\nulldelimiterspace}{\text{s}}}}\right)\left({\frac{4}{5}}\right)\\&=20\,{{\text{m}}\mathord{\left/{\vphantom{{\text{m}}{\text{s}}}}\right.\kern-\nulldelimiterspace}{\text{s}}}\\\end{aligned}

The motion of the ball in the horizontal direction is a linear motion and during this, the speed of the ball in the horizontal direction remains the same.

Since, the ball covers 60\,{\text{m}} in horizontal direction from Maya to reach to Max at the goalkeeping end, the ball will travel this distance at the speed of 20\,{{\text{m}} \mathord{\left/ {\vphantom {{\text{m}} {\text{s}}}} \right. \kern-\nulldelimiterspace} {\text{s}}}.

The time taken by the ball to reach Max at the goalkeeping end is:

\begin{aligned}t&=\frac{{{\text{distance}}}}{{{\text{speed}}}}\\&=\frac{{60\,{\text{m}}}}{{20\,{{\text{m}}\mathord{\left/{\vphantom{{\text{m}}{\text{s}}}}\right.\kern-\nulldelimiterspace}{\text{s}}}}}\\&=3\,{\text{s}}\\\end{aligned}

Thus, the soccer ball takes \fbox{3\,{\text{s}}} to reach the Max at the goalkeeping end.

A 30 ohm resistor and a 20 ohm resistor are
Reptile [31]

The current that would pass through the 30 ohms resistor is 2 A.

<h3>What is electric current?</h3>

Electric current is the rate of flow of electric charge round a conductor.

To calculate the electric current that would pass through the 30 ohms resistor, we use the formula below

Formula:

  • I = V/Rt........... Equation 1

Where:

  • I = Electric current passing through the 30 ohms resistor
  • V = Voltage
  • Rt = Total or effective resistance of the resistors.

From the question,

Given:

  • V = 100 volts
  • Rt = (30+20) ohms (since both resistors are connected in series)
  • Rt = 50 ohms

Substitute these values into equation 1

  • I = 100/50
  • I = 2 A

Hence, The current that would pass through the 30 ohms resistor is 2 A.

The statement that best describes the production of energy in the Sun is nuclei with less mass combine to form nuclei with more mass in the Sun’s core and release energy.

<h3>How is energy produced in the sun?</h3>

Sun is a major source of renewable energy to the Earth. This energy serves various purposes by living organisms.

However, the energy is generated as a result of nuclear fusion, which is the combination of smaller particles to form a larger one.

Therefore, the statement that best describes the production of energy in the Sun is nuclei with less mass combine to form nuclei with more mass in the Sun’s core and release energy.
