A factory has 1200 workers of which 720 are male and the rast are female what percent of workers are female
Answer:
Percent of Female Workers = 40%
Explanation:
The percentage of the female workers in the given group of workers can be easily found by the following formula:
[tex]Percent\ of\ Female\ Workers = \frac{No.\ of\ Female\ Workers}{Total\ No.\ of\ Workers}\ x\ 100\%[/tex]
where,
Total No. of Workers = 1200
No. of Female Workers = Total Workers - No. of Male Workers
No. of Female Workers = 1200 - 720 = 480
Therefore,
[tex]Percent\ of\ Female\ Workers = \frac{480}{1200}\ x\ 100\%[/tex]
Percent of Female Workers = 40%

In the example of a hammer hitting a nail, which is hit harder? the nail, the hammer, or they both hit equally?
Answer:
both hit qaulity
Explanation:
Newton's Third Law says that every interaction involves two forces - in this case (1) hammer pushes nail, and (2) nail pushes hammer. When a hammer hits a nail, Newton's Third Law says that the force that the hammer exerts on the nail is exactly the same size as the force the nail exerts on the hammer.
A car traveling towards east at 40 m/s and turns towards left and travels at same speed. The change in velocity is
Answer:
Explanation:
In physics the term velocity is always a vector. All that means is that it's got a direction with it. which also means this vehicle that was traveling in the east direction and then turned left is and is now , maybe traveling in a north direction. Making the guesses that the car was traveling due East and is now traveling due North, then the car has changed it's velocity by 40 m/s. By The Way do you happen to know how fast 40 m/s is? it's about 144 Kph :0 or about 90 MPH so this guy is also speeding :D, write him a ticket ... :P

Answer: I didnt understand it sorrryryyyyyyy
Explanation:
Two charges are separated by a distance r. The distance between the charges is tripled to 3r. If the original force between the charges was 45N what is the new force between the charges A.5N B.15N C.75N D.135N
Answer:
5N
Explanation:
The formula formula for calculating the force between charges is expressed as;
F = kq1q2/r²
If two charges are separated by a distance r and a force between them is 45N, then;
45 = kq1q2/r² ....1
If the distance between the charges is tripled to 3r, then;
F = kq1q2/(3r)²
F = kq1q2/9r² ... 2
Divide both expressions
45/F = (kq1q2/r²)/(kq1q2/9r²)
45/F = kq1q2/r² * 9r²/kq1q2
45/F = 9
9F = 45
F = 45/9
F = 5N
Hence the new force between them will be 5N

A ray of light strikes a plane mirror at an angle of incidence equal to 35°. The angle between
the incident ray and the reflected ray is
A)
70°
B)
0°
C)
55°
D)
35°
Answer:
55 degrees
Explanation:
A ray of light strikes a plane mirror at an angle of incidence. The angle between the incident ray and the reflected ray is 70°. The correct option is A.
What is law of reflection?The law states that angle of incidence of the incident ray is equal to the angle of reflection through a plane surface.
Here, angle of incidence of light on a plane mirror is 35°, then the angle of reflection will also be 35°.
i = r = 35°
Then the angle between the incident ray and the reflected ray will be
i +r = 35 + 35 =70°
Thus, the correct option is A.

What is nuclear reaction?Nuclear reactions is the nuclei transformation process in which one or more nuclides are produced from the collisions between an atomic nucleus and a subatomic particle (neutrons or protons)
In this reaction, the nucleus changes because, the number of protons or neutron decreases. New element with new atomic number and nucleus is formed.
