Explanation:
the moon doesn't fall to earth because of it's friction?
Answer:
The Moon does not fall towards Earth right now because Earth rotates itself. The energy from the Earth's own rotation around its axis is gradually tranferred into energy of the Moon's orbital motion. That's why the Earth's rotating speed decreases but the distance to the Moon increases.
Answer:
I think No since the gravitational force of earth is not eneogh to pull moon to it

How fast must a person lift a barbell with a weight of 635 N to a height of 2.43 meters in order to have a power of 482 W
Answer:
Time = 3.2 seconds
Explanation:
Given the following data;
Weight = 635 N
Height, h = 2.43 m
Power = 482 Watts
To find the time;
Power = mgh/time
But weight = mg = 635
Substituting into the formula, we have;
482 = (635 * 2.43)/time
482 = 1543.05/time
Time = 1543.05/482
Time = 3.2 seconds
What is the purpose of chloroplasts, and why do you think it is missing from the root hair cell?
Explanation:
Mitochondria are essential parts of many eukaryotes, but they are useless without oxygen. Therefore, chloroplasts are extremely important. They produce breathable air for life. Root hairs are seen to not have chloroplasts as their job is to collect water and nutrients.

Use la fórmula Densidad x Volumen = Masa Exprese su respuesta en Kg 2.La masa del sol es 2x10^30 Kg. ¿Cuántas masas solares se necesitan para completar la masa total del universo visible? Exprese su respuesta en gramos
Answer:
1. La cantidad de materia que hay en el Universo es 3,53x10⁵⁴ kg.
2. Se necesitan 1,8x10²⁴ masas solares para completar la masa total del Universo visible.
Explanation:
1. La cantidad de materia del Universo se puede calcular a través de su volumen (V) y de su densidad (d):
[tex] d = \frac{m_{u}}{V} = \frac{m}{\frac{4}{3}\pi r^{3}} [/tex]
En donde:
r: es el radio = d/2 = 8,8x10²⁶/2 m = 4,4x10²⁶ m
[tex]m_{u}[/tex]: es la masa del Universo =?
d: es la densidad = 9,9x10⁻²⁷ kg/m³
[tex]m_{u} = d*v = 9,9 \cdot 10^{-27} kg/m^{3}*\frac{4}{3}\pi (4,4 \cdot 10^{26} m)^{3} = 3,53 \cdot 10^{54} kg[/tex]
Entonces, la cantidad de materia que hay en el Universo es 3,53x10⁵⁴ kg.
2. La masa del sol es 2x10³⁰ kg, por lo que para completar la masa total del Universo visible se necesitan las siguientes masas solares:
[tex]N = \frac{m_{u}}{m_{s}} = \frac{3,53 \cdot 10^{54} kg}{2\cdot 10^{30} kg} = 1,8 \cdot 10^{24}[/tex]
Por lo tanto, se necesitan 1,8x10²⁴ masas solares para completar la masa total del Universo visible.

A car travels in 300 km in 3 hours. What can be determined?
Answer: If a car travels 300 km in 3 hours, then it’s speed will will be 100 km/hr. But in practical it depends upon type of car, condition of car, car's maximum speed and also the path in which car is travelling.. Because car can't travel in constant speed of 100 km/hr. So, if car have 120 km/hr as maximum speed than it's minimum speed will be 85–95 km/hr. And so the car travel 300 km in around 5 or 5 and half hours.

A force is used to lift mass to a height of 8 m does 1040 J of work. How much force is used?
Answer:
[tex]\boxed {\boxed {\sf 130 \ Newtons }}[/tex]
Explanation:
Work is the energy transferred to or from an object when force is applied to cause displacement. It is the product of force and displacement.
[tex]W=F*s[/tex]
The displacement (s) is 8 meters and the work (W) is 1,040 Joules. Substitute these values into the formula.
[tex]1040 \ J= F* 8 \ m[/tex]
First, let's convert the units. This will make the question easier later on. 1 Joule is equal to 1 Newton meter, so the 1040 J of work equal 1040 N*m.
[tex]1040 \ N*m= F * 8 \ m[/tex]
Since we are solving for the force (F), we must isolate the variable. It is being multiplied by 8 meters and the inverse of multiplication is division. Divide both sides by 8 m.
[tex]\frac {1040 \ N*m}{8 \ m}= \frac{F * 8 \ m}{8 \ m}[/tex]
[tex]\frac {1040 \ N*m}{8 \ m}=F[/tex]
The meters cancel out, hence our earlier unit conversion.
[tex]130 \ N = F[/tex]
A force of 130 Newtons is used.

An electric iron consumes energy at a rate of 840 W when heating is at the maximum rate and 360 W when the heating is at the minimum. The voltage is 220 V. What are the current and the resistance in each case?
Don't spam
Answer:
At maximum the current is 4A and resistance is 55Ω
At minimum the current is 1.636A and resistance is 134.45Ω
Explanation:
The computation of the current and the resistance in each case is shown below:
At the time when it is heated at max rate,
power, P = 840W
V = 220V
As We know that
P = VI
840 = 220 × I
I = 840 ÷ 220
I = 4 A
Now
R = V ÷ I
= 220 ÷4
= 55 Ω
Hence, the current is 4A and resistance is 55Ω
At the time When it is heated at minimum rate,
power, P = 360W
V = 220V
As We know that
P = VI
360 = 220 × I
I = 360 ÷ 220
I = 1.636 A
Now
R = V÷ I
= 220 ÷1.636
= 134.45 Ω
Hence, the current is 1.636A and resistance is 134.45Ω

A hockey puck slides with a constant velocity across a frictionless ice surface. In one paragraph, using your own words, describe the net force on the hockey puck and the observation which allowed you to draw that conclusion.
Answer:
The net force on the hockey puck is zero because it's acceleration is zero due to constant velocity.
The hockey will remain in it's uniform motion unless compelled by an external force.
Explanation:
[tex]from \: vector \: mechanics \\ a = \frac{dv}{dt} \\ but \: at \: constant \: velocity \\ \frac{dv}{dt} = 0 \\ hence : \: \: a = \frac{0}{dt} \\ a = 0[/tex]

A block is attached to the end of a horizontal ideal spring and rests on a frictionless surface. The block is pulled so that the spring stretches relative to its unstrained length. In each of the following three cases, the spring is stretched initially by the same amount. Rank the amplitudes of the resulting simple harmonic motion in decreasing order (largest first). (a) The block is released from rest. (b) The block is given an initial speed . (c) The block is given an initial speed .
Answer:
The answer is "a, c and b"
Explanation:
Its total block power is equal to the amount of potential energy and kinetic energy.Because the original block expansion in all situations will be the same, its potential power in all cases is the same.Because the block in the first case has no initial speed, the block has zero film energy.For both the second example, it also has the [tex]v_o[/tex] velocity, but the kinetic energy is higher among the three because its potential and kinetic energy are higher.While over the last case the kinetic speed is greater and lower than in the first case, the total energy is also higher than the first lower than that of the second.The greater the amplitude was its greater the total energy, therefore lower the second, during the first case the higher the amplitude.where is the center of the universe located? and any 16 or older guys on here who are down to talk?? i got a pad we can talk on :) (i'm 17)

Which energy change is caused by an endothermic chemical reaction?
A. An increase in temperature
B. Absorption of thermal energy
C. Release of light
D. Production of thermal energy
The energy change caused by an endothermic chemical reaction is the absorption of thermal energy. So, option B.
What is meant by endothermic reaction ?Endothermic reactions are defined as, those reactions in which the reactants take in heat energy from the environment to create products.
Here,
The endothermic reactions lower the temperature of their surrounding area, thereby creating a cooling effect.
When bonds in the reactants are broken, more energy is absorbed than is released when new bonds are generated in the products. This is known as an endothermic reaction.
A drop in the temperature of the reaction mixture is a characteristic of endothermic reactions.
In endothermic reactions, the enthalpy of the products of the reaction is greater than that of the reactants. Energy is absorbed from the surroundings.
Hence,
The energy change caused by an endothermic chemical reaction is the absorption of thermal energy.
