Answer:
Damaging effects of sewage dumps on human health include Cholera, Typoid and Dysentery.
Explanation:
Life-threatening human pathogens carried by sewage include cholera, typhoid and dysentery. Other diseases resulting from sewage contamination of water include schistosomiasis, hepatitis A, intestinal nematode infections, and numerous others.
Explanation:
I assume the acceleration calculated in part (b) is the 3.33 m/s² from your other question.
Use Newton's second law to find the total force:
F = ma
F = (60,000 kg) (3.33 m/s²)
F = 200,000 N
Since there are 2 engines, the thrust from each is half of this:
F = 100,000 N
In reality, there are forces other than thrust. There are also drag forces (rolling friction and air resistance).
From Newton's second law, if we increase the mass and keep the force the same, the acceleration decreases. So it would take longer to reach the take-off speed.
Answer:
Centripetal force,
Explanation:
It is given that,
Mass of the ball, m = 62 g = 0.062 kg
Length of the string, l = 72 cm = 0.72 m
Angle,
To find,
The centripetal force experienced by the ball.
Solution,
According to the attached free body diagram,
T = 0.716 N
The centripetal force will be experienced by the ball in horizontal direction. It is equal to :
So, the centripetal force experienced by the ball is 0.379 N.
Pressure is the force acting per unit area and increases with increase in the weight of a body.
<h3>What is pressure?</h3>
Pressure is defined as the force acting per unit area of a body.
Pressure depends upon the amount of force on an object and the size of the area the force pushes or pulls on.
The greater the amount of weight pressing on an object, the greater the amount of pressure.
Of the following objects air, ice, plastic, and gold, gold is the most dense.
A dense object will produce more pressure than one that is not dense since it exerts a greater force per unit area.
Solids exert pressure because gravity is pulling downward on the object.
It is not true that the human body has more pressure sensors in the legs than in the fingertips as pressure sensors are more in fingertips.
Therefore, pressure is the force acting per unit area and increases with increase in the weight of a body.

Answer:
Explanation:
As we know that amplitude of forced oscillation is given as
here we know that natural frequency of the oscillation is given as
here mass of the object is given as
angular frequency of applied force is given as
now we have
