Answer:
Time, t = 4.08 secs
Explanation:
<u>Given the following data;</u>
Initial velocity, U = 40m/s
To find the time, we would use the first equation of motion;
Where;
- U is the initial velocity.
- t is the time measured in seconds.
<em>Making time, t the subject of formula, we have;</em>
We know that acceleration due to gravity, g is 9.8m/s².
a = g = - 9.8m/s² because the ball is thrown in the opposite direction.
Also, the final velocity is equal to zero (0) because the ball reached its maximum height.
<em>Substituting into the equation, we have;</em>
Time, t = 4.08 secs
<em>Therefore, it will take the ball 4.08 seconds to reach the top. </em>
A static stretch is a type of stretch where you hold the position for a long time.

Answer:
1) Yes the direction of the magnetic field is found based on Fleming's Right Hand Rule
2) The pattern indicates the direction of the magnetic force field lines
Explanation:
1) The solenoid is the is the coil of electric conductor that when it carries an electric current produces a magnetic field
According to Fleming's Right Hand Rule, the direction of the magnetic field produced by a solenoid, depends on the direction of the current such that when the direction of the conventional current is in the direction of the wrapped fingers, the thumb points in the direction of the magnetic field which is North N.
2) The pattern of field lines inside the solenoid indicates the direction of the generated magnetic field moving from left to right within the solenoid as the electric current moves around in the direction shown in the diagram.
