Answer:
Explanation:
Ionic bonding is stronger than any of the given intermolecular forces, but is itself NOT an intermolecular force. Ionic bonds are a permanent chemical connection between two atoms, whereas intermolecular forces as a more transient and temporary attraction between independent molecules
The metallic bond is somewhat weaker than the ionic and covalent bond. Ionic bonds are strong electrostatic attraction forces formed between positive and negative ions. This bond is non-directional, meaning that the pull of the electrons does not favor one atom over another.
Ion-dipole forces are the strongest of the intermolecular forces. ... However, hydrogen bonds are still not as strong as ion-dipole interactions. In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.
Van der Waals forces are driven by induced electrical interactions between two or more atoms or molecules that are very close to each other. Van der Waals interaction is the weakest of all intermolecular attractions between molecules
Answer:
upper part second pic
Explanation:
if you observe the trend it increases with each lap and the guy increases the distance he has covered with each lap so distance increases with time
P = Momentum
M = Mass
t = time
v = velocity (speed)
J= Impulse
1.)
F = 100N
t = 5s
Change in momentum(P) = Ft
I see that this is not one of your equations but your equations do not work with this problem.
P = Ft
P = (100)(5)
P = 500 Ns
2.)
See if you can get this one by yourself from what I did on the last problem.
3.)
P = 25 kgm/s
M = 2.0 kg
So, you are looking for velocity (speed). Look for the equation that has momentum, mass and velocity.
Use the equation P = mv
25 = 2(v)
25 = 2v
25/ 2 = 2v/2
12.5 m/s = v
4.) Do the same for number 4.
P = 12 kgm/s
M = 1kg
P = mv
12 = 1v
12/1 = 1v/1
12 m/s = v
6.)
P = 100 kgm/s
V= 7.0m/s
P= mv
100 = m7.0
100/7 = 7.0m/7
14.28 kg = m
Try page 2 by yourself and message me or comment if you need more help. Just identify the variable you have and what you need to find and put them in an equation that fits. You can do this!!!!
Answer:
20 Joules
Explanation:
Work is done whenever a force moves a body through a certain distance in the direction of the force. So, work done is the product of force and distance moved.
Therefore, we have;
Work done = Force x distance
i.e Wd = Fs
Given that: F = 20 N and s = 1 m, then;
Wd = 20 N x 1 m
= 20 Nm
The work done by the father is 20 Joules(Nm).
Answer:
The answer is below!
Explanation:
Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases
Hope I helped!!
