Explanation:

The pressure exerted at the base will be "500 Nm".

Given values are:

Height,

5 cm or, 0.05 m

Base of container,

50 cm

The pressure exerted will be:

→ [tex]P = hdg[/tex]

By substituting the values, we get

Explanation:

reactants are on the laft side of arrow and products are on right side of arrow

The option that best represents a chemical reaction is Reactants → products. Thus, the correct option for this question is D.

What is a Chemical reaction?

A chemical reaction may be defined as a methodology through which one or more substances that are also called reactants, are significantly transformed into one or more different substances which are known as products.

The involvement of these reactants and products are either chemical elements or compounds. The mass of the chemical reaction remains the same but the state of matter may be altered. Some chemical reactions also involved the utilization of catalysts in order to proceed with the reaction fast by lowering its activation energy.

Therefore, reactants → products is an option that best represents a chemical reaction.  Thus, the correct option for this question is D.

What is 1.2 x 10^5 in standard form?

Answers

Answer in standard form is 120000

The standard form of the given exponential function is 120000.

By putting the number as a base and the number of repetitions as a little number to its upper right, a representation of repeated multiplications of the same number is known as an exponential form.

It is simpler to write repeated multiplication using base and exponents in the exponential form.

The equation f(x) = aˣ, in which the input variable x appears as an exponent and a as the base, describes an exponential function.

So, the given exponential function is,

1.2 x 10⁵

Here, 10 is the base and 5 is the exponent.

10⁵ = 100000

Therefore, the standard form of the given equation is,

The brakes used a coil system to convert the kinetic energy into potential energy stored in the brakes

The kinetic energy of the plane gets pushed into the air in front of it due to drag forces, causing the air to move, thus transferring the kinetic energy from the plane to the air

How long does it take a 100 kg rocket to increase speed from 10

Answers

Answer:

Explanation:

Using the formula t=vf-vo/a, where t=time, vf= final velocity, v0= initial velocity, and a= acceleration, we can solve for your problem.

Plug in known variables...

t=200-10/a

we can solve for a by using the formula F=ma where f=force, m= mass, and a=acceleration and rearranging it to solve for a.

a=F/m

Plug in known variables...

a=250N/100kg

a=2.5m/s^2

Plug in our newly found acceleration of 2.5 m/s^2 into our first equation and solve....

A 14-gauge copper wire of diameter 1.628 mm carries a current of 12.5 What is the potential difference across a 2.00 - m length of the wire? *p=1.47x10^-8

Answers

Answer:

[tex]V=1.76\times 10^{-4}\ V[/tex]

Explanation:

Given that,

The diameter of a wire, d = 1.628 mm

Radius, r = 0.814  mm = 0.000814m

Current, I = 12.5 mA

The length of the wire, l = 2m

The resistivity of the wire, [tex]\rho=1.47\times 10^{-8}\ \Omega-m[/tex]

We need to find the potential difference across the wire. We know that the resistance of the wire is given by :

[tex]R=\rho\dfrac{l}{A}[/tex]

Also, V = IR

[tex]\dfrac{V}{I}=\rho\dfrac{l}{A}\\\\V=\dfrac{\rho l I}{A}\\\\V=\dfrac{1.47\times 10^{-8}\times 2\times 12.5\times 10^{-3}}{\pi \times (0.000814)^2}\\\\V=1.76\times 10^{-4}\ V[/tex]

So, the potential difference of the wire is [tex]1.76\times 10^{-4}\ V[/tex].
