How and why can two lethal elements combine to form an essential
compound for health?
Answer:
Two lethal elements can combine to form an essential compound for health by undergoing a chemical reaction such that the properties of the individual elements are different from the properties of the product and are no more lethal
Example Mercury and Sulfur combine to form cinnabar which is used as a medicine to relieve pain, antiseptic, and to cure diseases
Mercury and sulfur combines because mercury readily combines with sulfur at high temperatures
Explanation:
Mercury is a lethal element that also has harmful effects on the neurological system
Sulfur is lethal when too much of it is consumed

True or false elastic energy is a type of kinetic energy
Answer:
True
Explanation:
The statement "elastic energy is a type of kinetic energy" is absolutely false.
What is Kinetic energy?Kinetic energy may be defined as a type of energy that is typically possessed by an object due to its motion. It is characterized as the work which is required in order to accelerate a body of a given mass from rest to its initiate velocity.
Elastic energy is a type of mechanical potential energy that is kept in reserve in the arrangement of a material or physical system as it is conquered by elastic deformations.
Elastic energy is a type of energy that is occurred when any objects are temporarily compressed, stretched, or typically disfigure in any manner.
Therefore, the statement "elastic energy is a type of kinetic energy" is absolutely false.

In mammals, the weight of the heart is approximately 0.5% of the total body weight. Write a linear model that gives the heart weight in terms of the total body weight. Use the model to find a) the weight of the heart of a human whose weight is 185 lbs. Answer in units of lbs.
Answer:
The weight of heart of a human is 0.93 lbs.
Explanation:
Given that,
Approximately weight of heart is 0.5 % of the total body weight.
Weight of human = 185 lbs
Let the the weight of total body is w and weight of heart is [tex]w_{h}[/tex].
We need to calculate the weight of heart of a human
Using given data
[tex]w_{h}=0.5\times w[/tex]
Where, h = weight of heart
w = weight of human
[tex]w_{h}=\dfrac{0.5}{100}\times 185[/tex]
[tex]w_{h}=0.93\ lbs[/tex]
Hence, The weight of heart of a human is 0.93 lbs.
Which of the following is an example of Newton’s first law of motion?
Sam’s bike hits a curb and he flies over the handlebars, onto the grass.
A feather and a brick are dropped from a ladder. The brick exerts a greater force when it hits the ground.
A person sits on a chair and pushes down, and the chair pushes upwards on the person.
Tires from a car push against the road, and the road pushes back.
Answer:
I think first one
Explanation:
Because his first law of motion was every object will remain at rest or uniform motion in a straight line
Answer:
Sam's bike hits a curb and he flies over the handlebars, onto the grass.
Explanation:
As we know that: Newtons first law of motion states that a body continues to remain in the inertia of rest or motion, unless it is forced to change by applying an unbalanced force. Sam's bike is in uniform motion when suddenly the curb(external force) hits it and makes Sam to fall.

Answer:
18.425 Joules
Explanation:
To figure this out we can simply use the W=Change in Kinetic Energy,
W = 1/2*.022*46^2-1/2*.022*21^2 (Note we can ignore the direction of the particles as we need to take the square of the velocity)
W=18.425 (By simplifying the expression)

ES 1. How fast must a truck travel to stay beneath an airplane that is moving 105 km/hr at an angle of 25 degrees to the ground?
Answer:
The truck must travel at a speed of 98.6677 km/hr to stay beneath the airplane
Explanation:
The given parameters are;
The velocity of the airplane, v = 105 km/hr
The direction of the airplane, θ = 25 degrees to the ground = 25°
Therefore, we have that the horizontal component of the velocity of the plane, vₓ is given as follows;
vₓ = v × cos(θ) = 105 km/hr × cos(25) ≈ 98.6677 km/hr
The vertical component of the velocity of the plane, [tex]v_y[/tex], is given as follows;
[tex]v_y[/tex] = v × sin(θ) = 105 km/hr × sin(25) ≈ 44.37 km/hr
The truck only has to travel at a speed equal to the horizontal velocity of the airplane to stay beneath the airplane
Therefore, the travelling speed the truck must be vₓ which is 98.6677 km/hr to stay beneath the airplane.

Answer:
increases
Explanation:

That as we said, that the more down they go, the more pressure will be on them, which means that the pressure will keep on increasing as you go down and down in the ocean.

The pumpkin travels 9.5\,\text m9.5m9, point, 5, start text, m, end text horizontally before it hits the ground. We can ignore air resistance.
Answer:
d = 27.522 m
Explanation:
The horizontal speed of a pumpkin, [tex]v_x=4\ m/s[/tex]
The horizontal distance covered by the pumpkin, [tex]d_x=9.5\ m[/tex]
We can assume to find the the pumpkin's vertical displacement during the throw.
Firstly we can find the time of flight for the pumpkin. It can be calculated as follows :
[tex]t=\dfrac{d_x}{v_x}\\\\t=\dfrac{9.5}{4}\\\\t=2.37\ s[/tex]
The vertical displacement during the throw is given by :
[tex]y=u_yt+\dfrac{1}{2}a_yt^2[/tex]
Here, [tex]u_y=0\ \text{and}\ a_y=-g[/tex]
So,
[tex]y=\dfrac{1}{2}gt^2\\\\y=\dfrac{1}{2}\times 9.8\times (2.37)^2\\\\y=27.522\ m[/tex]
So, the vertical displacement of the pumpkin is 27.522 m.

A capacitor has two parallel plates seperated by 2mm and is connected across a 50V battery. a. What is the electric field between the field? b. What is the surface charge density? c. How much charge is stored on each plate if the area is 0.1m^2. d. Calculate the capicitance e. How much energy is stored in this capacitor?
Answer:
a
[tex]E = 25000 \ V/m[/tex]
b
[tex]\sigma = 2.2125* 10^{-7} \ C/m^2[/tex]
c
[tex]q = 2.2125 *10^{-8} \ C [/tex]
d
[tex]C = 4.425 *10^{-10} \ F[/tex]
e
[tex]U = 5.531 *10^{-7} \ J[/tex]
Explanation:
From the question we are told that
The distance of separation is [tex]d = 2mm = 0.002 \ m[/tex]
The voltage is [tex]V = 50\ V[/tex]
The area is [tex]A =0.1m^2[/tex]
Generally the electric field is mathematically represented as
[tex]E = \frac{V}{d}[/tex]
=> [tex]E = \frac{50}{ 0.002}[/tex]
=> [tex]E = 25000 \ V/m[/tex]
Generally the capacitance mathematically represented is
[tex]C = \frac{\epsilon_o * A }{d}[/tex]
Here [tex]\episilon_o[/tex] is the permitivity of free space with value
[tex]\episilon_o = 8.85 * 10^{-12} C/(V⋅m [/tex]
=> [tex]C = \frac{ 8.85 * 10^{-12} * 0.1 }{0.002}[/tex]
=> [tex]C = 4.425 *10^{-10} \ F[/tex]
Generally the charge is mathematically represented as
[tex]q = C * V[/tex]
[tex]q = 4.425 *10^{-10} *50 [/tex]
=> [tex]q = 2.2125 *10^{-8} \ C [/tex]
Generally the charge density is mathematically represented as
[tex]\sigma = \frac{q}{A}[/tex]
=> [tex]\sigma = \frac{ 2.2125 *10^{-8}}{0.1}[/tex]
=> [tex]\sigma = 2.2125* 10^{-7} \ C/m^2[/tex]
Generally the energy stored in this capacitor is mathematically
[tex]U = \frac{1}{2} * CV^2[/tex]
=> [tex]U = \frac{1}{2} * (4.425 *10^{-10} ) * (50)^2[/tex]
=> [tex]U = 5.531 *10^{-7} \ J[/tex]
