Answer :-
Force is 70 meter² .Explanation :-
As per the provided information in the given question, Force is given as 700 Newton. Pressure is given as 10 Pascal. And, we have been asked to calculate the Area.
For calculating the Area , we will use the Formula :-
[tex] \bigstar \: \: \: \boxed {\sf { \: Area \: = \: \dfrac {Force}{Pressure \: } }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \Longrightarrow \: \: \: \sf {Area \: = \: \dfrac {Force}{Pressure}} [/tex]
[tex] \Longrightarrow \: \: \: \sf {Area \: = \: \dfrac {700}{10}} [/tex]
[tex] \Longrightarrow \: \: \: \bf {Area \: = \: 70} [/tex]
Hence :-
Area = 70 meter² .[tex] \underline {\rule {180pt}{4pt}} [/tex]
How can you make the work output of machine greater than the work input
Answer:
The only way to increase the work output is to increase the work input. You can't get more work out of a machine than you put into it. The moving parts of a machine must use some of the work input to overcome friction. Because of friction, the work output of a machine is always less than the work input.

After the right string is cut, the meterstick swings down to where it is vertical for an instant before it swings back up in the other direction. What is the angular speed when the meterstick is vertical?.
The Angular Speed of the Meterstick after it becomes vertical is given as:
= 5.800 rad/s. This is computed using the formula for conservation of energy.
What is Angular Speed?
Angular Speed is defined as the measure of how quick or fast the central angle of a body that is rotational is changing in relation to time. Please see the attached for the full question.
What is the solution for the Angular Speed of the phenomena described?Recall that the formula for conservation of energy is given as:
(1/2)(Iω²) = mg(L/4) where
L= Lenght and
m = Mass. Please refer to the attached questions.
Factoring the moment of inertia about the pivot, we solve for the angular speed using the following formula:
ω = [tex]\sqrt{(mgL)/2I}[/tex]
= [tex]\sqrt{(6g)/7L}[/tex]
Hence, the angular speed is:
ω = 8.800rad/s

A resistor of 4 ohms is connected isn series to a box speaker of unknown resistance. If a current of 0. 6A flows through the speaker when a voltage of 12V is applied across the combination, calculate: 1. The total resistance in the circuit. Ii. The resistance of the speaker ili. The voltage applied across the speaker.
Answer:
Explanation:
Part One
Current = 0.6 amps
Voltage = 12 volts
R = ?
R = E / I
R = 12/0.6
R = 20 ohms
Part 2
Rt = Rspeaker + R
Rt = 20 ohms
R = 4 ohms
Formula
Rt = Rspeaker + R
20 = Rspeaker + 4 Subtract 4 from both sides
Rspeaker = 16 ohms
Part 3
Rspeaker = 16 ohms
I = 0.6 ohms
E = 0.6 * 16
E = 9.6

What is an electric generator?An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.
When strong magnets are used, a strong flux is produced, and the motor becomes more powerful. Internal flux has a significant impact on coil strength.
Increasing current results in greater power. In the same way, shortening the distance between magnets makes the motor stronger by increasing flux and torque.

Answer:
The mass=0.169
The height=57.8
The power=1.63 watts
Explanation:
The formula for mass is 2KE/v^2
v=34×34 KE=98 therefore 2*98/34^2=0.169
The formula for height is v^2/2g
v=34*34 therefore 34^2/2*10=57.8
