As distance increases, the amount of force needed decreases.
Answer:
ANGLE is 35.3 degree celcius
Explanation:
Given data:
mass m and 3m
initial speed Vi
particle with mass m is moving toward left while particle with mass 3m is moving toward right
By using conservation of momentum :
conservation of energy :
After collision, particle with mass m moves at right angles, thus by considering conservation of momentum in x & y direction,
x direction : 
y direction : 
subsitute these value in energy conservation
35.3 degree from x-axis
ANY DENSE OBJECT
A mathematical equation for density is: Density = mass/volume or D = m/v. If something has a large mass compared to its volume, it has a high density. This is like a set of weights which can be small but heavy. But if an object has a small mass compared to its volume it has a lower density.
Pls give me a brainliest if this helps thx
Answer:
Amine have higher boiling points than hydrocarbons.
Explanation:
Primary, secondary and tertiary amines have higher boiling points than hydrocarbons because they can engage in intermolecular hydrogen bonding.
Amines has three classes
1. Primary amines
2. Secondary amines
3. Tertiary amines
All this classes of amines have higher boiling point than hydrocarbons due to C-N bond in them
This is because amines can engage in hydrogen bonding with water, amines of low molar mass are quite soluble in water.
Amines are having higher boiling points than hydrocarbons, as C-N bond in amines is more polar than a C-C bond in hydrocarbons. Due to the polar nature of amines, it forms intermolecular H-bonds and exists as associated molecules.
Answer:
1.53m
Explanation:
Given parameters:
Mass of box = 3kg
Gravitational potential energy = 45J
Unknown
Height of the box = ?
Solution:
To solve this problem;
Gravitational potential energy = mgh
m is the mass
g is the acceleration due to gravity
h is the height
45 = 3 x 9.8 x h
h = 1.53m
