What is the human life valuation?It was illustrated that the motorcycle riders to wear helmets reduces the probability of a motorcycle fatality from 0.3 percent to 0.2 percent over the lifetime of a motorcycle rider.
Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true.
Since the cost of a lifetime supply of helmets is $500, the lifetime human life = = 500 / (0.3 - 0.2) × 100
= 500 / 0.1 × 100
= 5000 × 100

three balls are in water. ball 1 floats, with half of it exposed above the water level. ball 2, with a density less than the density of water is held below the surface by a cord anchored to the bottom of the container, so that it is fully submerged. ball 3, of same radius as ball 2, but of greater mass, is suspended from a rope so that it is fully submerged.
The correct statement about the ball 1 is the magnitude of buoyancy force is equal to that of ball's weight.
The upward force exerted on an object that is wholly or partially immersed in a fluid is called upthrust.
Ball 1 is floating on water.
Weight of the ball 1 is Fg = m₁g is acting vertically downward.
Force of buoyancy Fb = ρvg is acting vertically upwards
Net force acting on the ball is zero, Fg = Fb
As the ball 1 floats without sinking, it is in equilibrium.

A parallel plate capacitor has a capacitance of C=fracepsilon_0 Ad, where A is the area of the plates and d is the distance between them. 1) If the area of the plates A_1 grows, then A_1>A C_1=fracepsilon_0 A_1d>fracepsilon_0 Ad C_1>C, which means that the capacitance also grows.
2) If the distance between the plates is increased by d_1, the capacitance decreases because d_1>d C_1=fracepsilon_0 Ad_1 fracepsilon_0 Ad C_1C.
3) Since capacitance is directly proportional to plate area, capacitance also increases with plate area.
Because capacitance is inversely proportional to plate separation, capacitance decreases as plate separation increases.

specific features are created using scrum methodology according to four distinct phases. which of the following places these phases in the correct order?
Analysis, Design, Build, Test is the correct order specific features are created using scrum methodology according to four distinct phases
Explain the distinct phase of force.A force that is applied to an object by a person or another object is referred to as an applied force. When someone pushes a desk across the room, there is an applied force acting on the object. The applied force is the force that the person exerts on the desk. The force of gravity is the attraction that the earth, moon, or other enormously large object has on another object. The normal force is the force exerted by one object in contact with another stable object. The friction force is the force exerted by a surface when an object moves or attempts to move across it.

you have three light bulbs; bulb a has a resistance of 240 q, bulb b has a resistance of 192 q, and bulb c has a resistance of 144 q. each of these bulbs is used for the same amount of time in a setup like that in the drawing. in each case the speed of the rod and the magnetic field strength are the same. rank the setups in descending order, according to how much work the hand in the drawing must do (largest amount of work first).
The correct sequence will be: A, B, C
Given,
Resistance A = 240 Ω
Resistance B = 192 Ω
Resistance C = 144 Ω
We know that the resistance has relations with Current (I) and Voltage (v)
But to find the work done by the hand,
We will apply the formula of the work,
W = VIt
Replacing V with R/I
Work = (R/I)*I*t
Work= R*t
The time given is same.
So here,
Work = Resistance,
By this derivation, the highest resistance will do the highest amount of work.
Therefore, the work done by Resistance A will be the most and then the work by resistance B and then the work by resistance C.
