The four wheels of a car are connected to the car's body by spring assemblies that let the wheels move up and down over bumps an

d dips in the road. When a 68 kg (about 150 lb) person sits on the left front fender of a small car, this corner of the car dips by about 1.2 cm (about 1/2 in).
If we treat the spring assembly as a single spring, what is the approximate spring constant?

Answer:

The approximate  spring constant is  k =  55533.33 \  N/m

Explanation:

From the question we are told that

   The  mass of the person is  m =  68 \ kg

     The  dip of the car is  x =  1.2 \ cm  =  0.012 \ m

Generally according to hooks law  

        F  =  k * x

here the force F is the weight of the person which is mathematically represented as

         F =  m * g

=>    m * g  =  k * x

=>     k  =  \frac{m * g }{x }

=>    k  =  \frac{68 *  9.8}{ 0.012}

=>   k =  55533.33 \  N/m

Which of the following describes how the current in a circuit can be increased? Select all that apply.
Anettt [7]

Answer:

B. and D. would be my best guess.

Explanation:

The reason why is because if you lower the resistance, the voltage will be higher, and if you higher the voltage, the resistance would be lower and the voltage would higher.

The concrete slab of a basement is 11 m long, 8 m wide, and 0.20 m thick. During the winter, temperatures are nominally 17 C and
Lunna [17]

Answer:

Q = - 4312 W = - 4.312 KW

Explanation:

The rate of heat of the concrete slab can be calculated through Fourier's Law of heat conduction. The formula of the Fourier's Law of heat conduction is as follows:

Q = - kA dt/dx

Integrating from one side of the slab to other along the thickness dimension, we get:

Q = - kA(T₂ - T₁)/L

Q = kA(T₁ - T₂)/t

where,

Q = Rate of Heat Loss = ?

k = thermal conductivity = 1.4 W/m.k

A = Surface Area = (11 m)(8 m) = 88 m²

T₁ = Temperature of Bottom Surface = 10°C

T₂ = Temperature of Top Surface = 17° C

t = Thickness of Slab = 0.2 m

Therefore,

Q = (1.4 W/m.k)(88 m²)(10°C - 17°C)/0.2 m

<u>Q = - 4312 W = - 4.312 KW</u>

<u>Here, negative sign shows the loss of heat.</u>

What is the relationship between DNA and mutation
Scrat [10]

Answer:

A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation

Iron man wears an awesome ironsuit.He is flying over high current carrying wire. Will he be affected?
frozen [14]

Answer:

According to super hero logic , nothing will happen to him.

But according to science , yes he will get current shock but good news is that he wouldn't get elected until he is in contact with the wires.

He may / may not be affected but his suit will be damaged for sure as it is made of metal.

HOPE THIS HLEP AND PLSSSSS MARK AS BRAINLIEST AND THNXX :)
