Answer:I think it would be 0
Explanation:
Both are pushing with 100n therefore it will not move
explanation:
the forces are moving in opposite directions which means 1 force is negative while the other is positive and therefore the two forces will substract rather than add.
if they were in the same direction you would add them

A 1200kg car traveling at 45m/s slams on its breaks and slides to a stop. If the coefficient of kinetic friction between the car and the road is 0.85 determine how far the car slides
Answers
Given :
A 1200 kg car travelling at 45 m/s slams on its breaks and slides to a stop.
If the coefficient of kinetic friction between the car and the road is 0.85 .
To Find :
How far the car slides.
Solution :
Acceleration is given by :
[tex]ma = \mu_kmg\\\\a = \mu_kg\\\\a = 0.85\times 10\ m/s^2\\\\a = 8.5\ m/s^2[/tex]
Distance covered is :
[tex]2as=u^2-v^2\\\\s = \dfrac{u^2-v^2}{2a}\\\\s=\dfrac{45^2-0^2}{2\times 8.5}\\\\s=119.12\ m[/tex]
Therefore, distance covered is 119.12 m.
Hence, this is the required solution.

20 g of water (specific heat of water is 4.18 J / g °C) undergoes a temperature change from 25° C to 20° C. How much heat energy moved from the water to the surroundings?
Answers
Answer:
418J
Explanation:
Given parameters:
Mass of water = 20g
Specific heat capacity of water = 4.18J/g°C
Initial temperature = 25°C
Final temperature = 20°C
Unknown:
Amount of heat lost to the surroundings = ?
Solution:
The amount of heat lost to the surrounding is the same as the quantity of heat needed to take down the temperature of the water.
Now, to solve this problem, use the mathematical equation below;
H = m c (T₂ - T₁)
H is the amount of heat
m is the mass
c is the specific heat capacity
T is the temperature
1 and 2 are initial and final states.
Now insert the parameters and solve;
H = 20 x 4.18 x (20 - 25)
H = -418J
The quantity of heat the moved from water to the surrounding is 418J

Answers
Answer:
Explanation:
We shall represent vector B and C in terms of i and j .
B = 5 cos115 i + 5 sin115 j
= -2.11 i + 4.53j
Similarly
C = 4 cos255 i + 4 sin225 j
= -1.04 i -3.86 j
R = B + C
= -2.11 i + 4.53j -1.04 i -3.86 j
= -3.15 i + .67 j
magnitude of R
= √( 3.15² + .67² )
= √( 9.92 +.45 )
= 3.22
Angle Ф
TanФ = - .67 / 3.15
= - .21
Ф = - 12⁰
= 180 - 12
= 168 degree counterclockwise from positive x axis.

Answers
Answer:
the answer is a low melting point
Explanation:
on edge
Low melting point is the most important property of covalent compounds that makes them useful for making candle wax.
A molecule created by covalent bonding whereby the atoms possess one or much more pair of valence electrons is referred to as a covalent compound. Covalent compounds or ionic compounds are the two groups into which chemical compounds are often divided.
Ionic compounds are composed of atoms or molecules that have gained or lost electrons, causing them to become electrically charged. Ionic compounds are created when ions with opposing charges come together, typically when a metal interacts with a nonmetal. Low melting point is the most important property of covalent compounds that makes them useful for making candle wax.
