Hydrogen bonds
Metallic bonds
Ionic bonds
Explanation:
This list orders the types of forces from weakest at the top to strongest at the bottom. Van der Waals forces are relatively weak intermolecular forces, followed by hydrogen bonds which are stronger. Metallic bonds are even stronger, and ionic bonds are the strongest among the listed forces.

Calculate the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.
Answer: The rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
Explanation:
The rate of energy transfer from one point to another is known as power.Its SI. unit is Watt.Formula to compute power:
Power = [tex]I^2 R[/tex], I = cureent, R = resistance.
Given R = 5 ohm , Current = 0.5 A.
Then, power = [tex](0.5)^2\times 5=0.25\times5=1.25\ watt[/tex]
Hence, the rate of energy transfer by a 5 ohms resistor when there is a current of 0.2 A in it.= 1.25 watt.
when operating a heater of 1500 watts for 3 hours per day the consumed energy and the total cost of 25 dirhams during a month (30 days) are ... and ...?
Answer:
I. Consumed energy = 4.5Kwh
II. Total cost = 3375 Dirhams
Explanation:
Given the following data;
Power = 1500W
Time = 3 hours
To find the energy consumption;
Energy = power * time
Substituting into the equation, we have;
Energy consumption = 1500 * 3
Energy consumption = 4500 watt-hour = 4.5Kwh (1 Kilowatts is equal to 1000 watts)
To find the total cost;
Daily cost = Energy consumption * cost
Daily cost = 4.5 * 25
Daily cost = 112.5 Dirham
Therefore, monthly cost = 112.5 * 30
Monthly cost = 3375 Dirham.
Which wave, A or B, has higher energy?
A
O A, because it has a higher amplitude
OB, because it has a higher amplitude
O A, because it has a lower amplitude
OB, because it has a lower amplitude
АЛЛА
B
Answer:
Wave A.
Explanation:
The energy of a wave is directly proportional to the square of the amplitude.
If a wave has higher amplitude, it will have more energy. On the other hand, a wave having lower amplitude, it will have less eenergy.
In this case, we need to tell which wave has higher energy. Hence, the correct option is A because it has a higher amplitude.

a car is moving at 4m/s has 500N force driving it forward and air resistance of 500N. Describe the motion of the car
Answer:
See the explanation below.
Explanation:
We know from Newton's second law that the sum of forces on a body is equal to the product of mass by acceleration. In this way, we have the following equation.
∑F = m*a
where:
∑F = sum of the forces [N] (units of Newtons)
m = mass of the car [kg]
a = acceleration [m/s²]
Therefore we have two forces one that drives the car forward and another that opposes the movement.
[tex]500-500 = m*a\\m*a=0\\a=0[/tex]
This tells us that the acceleration is zero and therefore the movement is with constant speed. That is, the speed does not vary during the movement of the vehicle.
3 ways that asteroids are like planets
Answer:
1.Asteroids aren't all round like planets. They have jagged and irregular shapes.
2.Some asteroids are hundreds of miles in diameter, but many more are as small as pebbles.
3.Most asteroids are made of different kinds of rocks, but some have clays or metals, such as nickel and iron.
Explanation:
it is simple really u just need to remember that astorids do not orbit a sun they crash into things like planets and mess them up really bad if they hit our sun which might happen it will just burn up because our sun is so hot that it can burn stuff if a astorid hits earth it wont be to bad for our earth at all it might cause some damage but we will be fine.

Which has more kinetic energy, a 4.0 kg bowling ball moving at 1.0 m/s or a 1.0 kg
bocce ball moving at 4.0 m/s? Explain your answer
Answer:
The kinetic energy of bocce ball is more.
Explanation:
Given that,
Mass of a bowling ball, m₁ = 4 kg
Speed of the bowling ball, v₁ = 1 m/s
Mass of bocce ball, m₂ = 1 kg
Speed of bocce ball, v₂ = 4 m/s
We need to say which has more kinetic energy.
The kinetic energy of an object is given by :
[tex]E=\dfrac{1}{2}mv^2[/tex]
Kinetic energy of the bowling ball,
[tex]E_1=\dfrac{1}{2}m_1v_1^2\\\\E_1=\dfrac{1}{2}\times 4\times (1)^2\\\\E_1=2\ J[/tex]
The kinetic energy of the bocce ball,
[tex]E_2=\dfrac{1}{2}m_2v_2^2\\\\E_2=\dfrac{1}{2}\times 1\times (4)^2\\\\E_2=8\ J[/tex]
So, the kinetic energy of bocce ball is more than that of bowling ball.
An 800 N man climbs 5 m up a ladder. How much gravitational potential energy does he gain?
Answer:
4000J
Explanation:
Given parameters:
Weight of the man = 800N
Height of ladder = 5m
Unknown:
Gravitational potential energy gained = ?
Solution:
The gravitational potential energy is due to the position of a body.
Gravitational potential energy = weight x height
Now insert the parameters;
Gravitational potential energy = 800 x 5 = 4000J

What is the magnitude of the normal force?
Choose 1 answer:
The magnitude of the normal force is to be considered as the mg cos θ when the box of mass m is at rest.
What is magnitude?In terms of physics, it refer to the maximum size where it should be extended also it defined the object direction. It is factor for vector and the scalar quantities.
When the box of mass m should be at rest so here the ramp should be an angle so here the weight should be perpendicular to the string.

A 1,200 kg car travels at 20 m/s. what is its momentum?
Answer:
The answer is 24 000kgm/s.
Explanation:
Given that the formula for momentum is p = m×v where m represent mass and v is speed :
let m = 1200, v = 20
p = m × v
p = 1200 × 20
p = 24 000 kgm/s

POSS An apple with a mass of 2 kg falls from a tree with an acceleration of 9 "What is the net force of the apple as it hits the ground?
Answer:
F = 19.62[N]
Explanation:
By means of Newton's second law which tells us that the sum of the forces on a body is equal to the product of mass by acceleration, we can determine the force.
[tex]F=m*a[/tex]
where:
F = force [N]
m = mass = 2 [kg]
a = gravity acceleration = 9.81 [m/s²]
Now replacing:
[tex]F=2*9.81\\F=19.62[N][/tex]
