How does adding thermal energy change the intermolecular force between atoms or molecules in an object?
ryzh [129]

Answer:

Weak intermolecular forces, low thermal energy. When an object such as liquid becomes a solid in form, this is sometimes caused by drop of heat, kinetic, energy in an object. And fast if there's weak molecular interaction.

. Draw a Cartesian coordinate system on a sheet of paper. On this Cartesian coordinate system, draw each vector to scale, starti
Triss [41]

Answer:

a) the first vector has magnitude 58 cm and the angle is 15 measured clockwise from the positive side of the x-axis

b) the second vector, the magnitude is 55.7 cm and the angle is 35 half from the negative side of the x-axis in a clockwise direction

c) the magnitude is 54.2 cm with an angle of 18 measured counterclockwise from the x-axis

Explanation:

For this exercise we draw a Cartesian coordinate system in this system: East coincides with the positive part of the x-axis and North with the positive part of the y-axis.

a) the first vector has magnitude 58 cm and the angle is 15 measured clockwise from the positive side of the x-axis

b) the second vector, the magnitude is 55.7 cm and the angle is 35 half from the negative side of the x-axis in a clockwise direction

c) the magnitude is 54.2 cm with an angle of 18 measured counterclockwise from the x-axis

In the attachment we can see the representation of the three vectors

What is the average speed of a commercial jet that travels from New York to Los Angeles 4800 kilometer in six hours
Alex Ar [27]

Answer: 800 km/h

Explanation:

Use equation for average speed

V=S/t

where S is distance

           t is time

S=4800Km

t=6h

---------

V=S/t

V=4800Km/6h=800 Km/h

The weight of the body varies from place to place but the inertia of the body remains the same. Why?
Kipish [7]

The weight changes from place to place as the weight is a vector quantity as well as a dependent quantity. Therefore, weight seems to be varying but the inertia is not.

<u>Explanation: </u>

The weight as already known well, is not a universal constant, whereas the mass is. As the weight is a product of mass of the body and the gravitational acceleration working on it, it varies as the factor of acceleration involved makes it a vector quantity.

And thus be dependent upon the direction too. Inertia of the body is an independent factor, on the other hand, an inherent property and so does not change.

A wire with a mass of 1.14 g/cm is placed on a horizontal surface with a coefficient of friction of 0.200. The wire carries a cu
anzhelika [568]

Answer: B=0.0162T

Explanation:

let this sign be ∅ (titha in degrees)

let coefficient of friction of 0.200 be u

and i be current i= 1.41A

mass m=1.14g/cm m=0.0114g/m

To find the magnetic field from the north will be:

tan ∅= u

∅=tan^{-1}(0.200

∅=11.3°

The direction:

i L*B cos(∅)=  umg

divide both by iLcos(∅) to find B

B= \frac{umg}{iBcos(∅)}  where m=\frac{m}{L}

B= \frac{u(m/L)g}{icos(∅)}

B= \frac{0.200*0.0114*9.81}{1.41*cos(11.3)}

B=0.0162T
