Explanation:
the density of silver at 0°C is 10310 kg/m^3 and the coefficient of linear expansion is 0.000019/°C . calculate its density at 100°C ?
Explanation:
The relative change in length of the edges of a cube are the coef times the change in temperature.
One meter expands to (1 + coef x 100C) = 1.0019 meter
Divide the mass by this number cubed to correct for volume expansion.
10310 kg / 1.00571 = 10251 kg/m3

PLEASE HELP DUE IN ALMOST AN HOUR PLEASE
Answer:
Below
Explanation:
4. You can use this formula to calculate the acceleration of an object
acceleration = velocity / elapsed time
Plugging our values in....
acceleration = 1700 m/s / 25 s
= 68 m/s^2
5. You can use this formula to calculate the final velocity of an object
finalvelocity = initialvelocity + (acceleration) (time)
Plugging our values in....
finalvelocity = 1.5 m/s + (2.4 m/s^2) ( 3 seconds)
= 8.7 m/s
Hope this helps! Best of luck <3

What is the acceleration of the car in initial 2 seconds [ans:20m/s^2
Answer:
[tex]accelaration = \frac{v}{t} \\ = in \: intial2sec \: v = 40 \\ a = \frac{40}{2} = 20 \frac{m}{ {se}^{2} } \\ thank \: you[/tex]
Answer:
20 m/s^2
Explanation:
v = u + at
Velocity:-
u = 0
v2 = 40
v = v2 - u = 40 - 0 = 40
Time:-
t2 = 2
t1 = 0
t = t2 - t1 = 2 - 0 = 2
Substituting v and t in formula,
v = u + at
40 = 0 + (a)(2)
2a = 40
=> a = 40/2
=> a = 20

What happens to the weight of an object when it is taken from Earth to the Moon? why ?
Answer:
So, if a body is taken to moon, the moon attracts the body with a force less as compared to the attraction force by the earth. Hence the weight decreases.

Hopefully it is helpful...If the density of a liquid is 20gcm - 3 height is 4cm and gravitational field strength is 10 N kg, the pressure of the liquid is
Answer:
Pressure is 1.96 × 10^12 Pa
Explanation:
[tex]{ \bf{pressure = \frac{force}{area} }}[/tex]
height = 4 cm = 0.04 m
density = 20 g/cm³ = 20,000 kg/m³
But for force:
[tex]{ \sf{force = mass \times acceleration}} \\ { \sf{force = ( \frac{density}{volume} ) \times acceleration}} \\ \\ { \sf{force = ( \frac{20000 }{0.04 {}^{3} }) \times 10 }} \\ \\ { \sf{force = 3.13 \times {10}^{9} \: newtons}}[/tex]
For area:
[tex]{ \sf{area = 0.04 \times 0.04 = 0.0016 \: m {}^{2} }}[/tex]
[tex] { \tt{pressure = \frac{3.13 \times {10}^{9} }{0.0016} }} \\ \\ = { \tt{1.96 \times {10}^{12} \: pascals}}[/tex]
You have 50L of water, it froze. So find its new volume. Density of water is 1000kg/m^3 or 1kg/L, density of ice is 920kg/m^3 or 0.92kg/L.
Answer:
D (density) = Mass / Volume
V (ice) = Mass / Density = 50000 g / .92 kg / L
V = 50 kg / .92 kg / L
1 Liter of water weighs 1 kilogram = 50 L weighs 50000 g
V = 54.3 L the mass does not change upon the change of phase (freezing)

An element has six valence electrons. Which ionic charge will its ion carry?(1 point)
2–
2+
6+
6–
Answer:
It's 2–
Explanation:
Usually, in ionic bonds, these elements will receive 2 electrons, so its ion will carry a 2– charge
The ionic charge its ion will carry will be 2-
An element is required to have 8 electrons in its outermost shell to assume it's full octet configuration.
The statement above of course excludes Hydrogen and helium which have only 1 and 2 electrons respectively.
An element with 6 Valence electrons would require 2 electrons to assume the full octet configuration.
As such, it is liable to accept 2 electrons from an electropositive element or group of elements to complete it's octet.
Therefore, accepting 2 electrons adds 2 negative charges and consequently, the ionic form of the element carries a 2- ionic charge

The force of gravity on the moon is only 16.6% the force of gravity on Earth. For each item listed in the table below, fill in what its weight would be on the moon?
==> Take an Earth weight. Don't forget the unit.
==> Multiply it by 0.166 .
==> The product is its Moon weight. Don't forget the unit.
Example:
If I weigh 1,000 lbs on Earth.
Multiply 1,000 lbs by 0.166 .
I weigh 166 lbs on the Moon
The complete table is as follows -
ITEM W(E) W(M)
Apple 150 g 25 g
Hammer 1.5 lbs 0.25 lbs
Person 180 lbs 30 lbs
Blue whale 200 tons 33.3 tons
We have the force of gravity on the moon is only 16.6% the force of gravity on Earth.
We have to fill the table given in the question.
Define Gravity in Physics.In physics, gravity is a fundamental interaction which causes mutual attraction between all things with mass or energy. The gravitational force between two bodies of mass 'm' and 'M' separated by a distance 'r' apart is given by -
[tex]$F = \frac{GMm}{r^{2} }[/tex]
According to the question, we have -
Force of gravity on the moon is only 16.6% the force of gravity on Earth.
This means that for an object of mass 'm' -
F(M) = 16.6% of F(E)
This means that a person would weigh six times less on the moon than they do on Earth -
W(moon) = [tex]\frac{1}{6}[/tex] W(earth)
Let's complete the table -
ITEM W(E) W(M)
Apple 150 g 1/6 x 150 = 25 g
Hammer 1.5 lbs 1/6 x 1.5 = 0.25 lbs
Person 180 lbs 1/6 x 180 = 30 lbs
Blue whale 200 tons 1/6 x 200 = 33.3 tons
