Required
Gravitational force
Solution
Newton's Gravity Law:
[tex]\rm F=G.\dfrac{m_1.m_2}{r^2}[/tex]
with F = gravitational force,
G = gravitational constant,
m1, m2 = mass of object,
r = distance between two objects.
Input the value :
F = (6.67.10⁻¹¹N.m² / kg² x 1500²) : 50²

What is the mass, in grams, of 2.00 moles of H2O?
Answers
Answer:
36g
Explanation:
Given parameters:
Number of moles of H₂O = 2moles
Unknown:
Mass of H₂O = ?
Solution:
To solve this problem, use the expression below:
Mass of H₂O = number of moles x molar mass
Molar mass of H₂O = 2(1) + 16 = 18g/mol
Mass of H₂O = 2 x 18 = 36g

When electricity moves through a metal wire, the wire is
A. A resistor
B. A conductor
C. an insulator
D. a power supply
Answers
When electricity moves through a metal wire, the wire is option B. A conductor.
What is a Conductor?Conductors are materials that allow electricity to flow easily through them. An electric current flows when electrons move through a conductor, such as a metal wire. The moving electrons can collide with the ions in the metal. This makes it more difficult for the current to flow and causes resistance.The flow of electricity through a wire is the flow of electrons. An electron is a negatively charged subatomic particle. In electrical conductors, the flow of electricity results from the movement of electrons from one atom to the next.To learn more about conductors, refer to: https://brainly.com/question/27533161

During the course of a trajectory, is the vertical component of the velocity a constant or a changing value? ___________________ If it is a changing value, then describe its changes (increasing, decreasing, or ...)
Answers
Answer:
1) Changing value
2) The velocity is decreasing for upward motion and increasing for downward motion due to gravitational force
Explanation:
1) A trajectory is the motion of an object which is being acted upon by specified forces. The flight path of an object in projectile motion is its trajectory
During the course of a trajectory, the vertical component of the velocity, [tex]v_y[/tex], is a changing value
2) The vertical component of the velocity first decreases, during the upward motion, according to the following equation;
[tex]v_y[/tex] = [tex]u_y[/tex] - g·t
Where;
[tex]v_y[/tex] = The vertical component of the velocity after a given time, t
[tex]u_y[/tex] = The initial vertical velocity
t = The time of motion of the trajectory
g = The acceleration due to gravity ≈ 9.8 m/s²
When the vertical velocity of the object decreases to zero, which is the point at which the object reaches the maximum height of its motion, the direction of the vertical motion of the object reverses, and object begins to accelerate and increase its velocity downwards according to the following equation;
[tex]v_y[/tex] = [tex]u_y[/tex] + g·t
Therefore, the velocity of the object is decreasing on its way up, and then increasing on its way down.
A rocket has a mass of 80,000 kg and accelerates at a rate of 35 m/s2. Calculate the force that provides this acceleration,
Answers
Explanation:
Given
Mass(M) = 80,000 kg
Acceleration (a) = 35 m/s²
Force (F) = ?
We know we have the formula
F = m * a
= 80000 * 35
= 2800000
= 2.8 * 10 ^ 6 N
The force is 2.8 * 10 ^ 6 N.
Hope it will help :)❤
If a rocket has a mass of 80,000 kg and accelerates at a rate of 35 m/s2. then the force that provides this acceleration would be 2800000 Newtons.
What is Newton's second law?Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.
The mathematical expression for Newton's second law is as follows,
F = m*a
As given in the problem we have to find the force that provides the acceleration of 35 meters / second², if the rocket has a mass of 80,000 kg,
The force acting on the rocket = 80,000 × 35
= 2800000 Newtons
Thus, the force acting on the rocket would be 2800000 Newtons.

Flag In reaching her destination, a backpacker walks with an average velocity of 1.34 m/s, due west. This average velocity results because she hikes for 6.44 km with an average velocity of 2.68 m/s, due west, urns around, and hikes with an average velocity of 0.447 m/s, due east. (a) How far east did she walk? (b) If she did not turn around and walked due east, how many hours would it take her to reach her destination with an average velocity of 1.34m/s due west?
Answers
Answer:
[tex]s_2=-806m[/tex]
Explanation:
From the question we are told that
Velocity 1 [tex]v=1.34m/s \angle west[/tex]
Distance [tex]d=6.44km=>6440m[/tex]
Velocity 2 [tex]v_3=2.68m/s[/tex]
Velocity 3 [tex]v_3=0.447m/s \angle east[/tex]
Generally the equation for VT is mathematically given by
[tex]VT=v_1t_1 +V_2t_2[/tex]
[tex]VT=2.68(2400)-0.447t_2[/tex]
[tex]1.34t_1+1.34t_2=2.68(2400)-0.447t_2[/tex]
[tex]t_2=1804s[/tex]
Therefore
[tex]s_2=v_2t_2=(-0.447)(1804)[/tex]
[tex]s_2=-806m[/tex]
What is the molar mass of Sodium Hydroxide, NaOH?
Answers
Answer:
40g/mol
Explanation:
The molar mass of a compound is the mass in grams of one mole of the substance.
To find the molar mass of NaOH;
a. Atomic mass of Na = 23g
O = 16g
H = 1g
b. So, the NaOH will have a molar mass of:
23g + 16g + 1g = 40g/mol
The molar mass of NaOH is 40g/mol
On the way home from school, you notice the speedometer on the car is at 5,200 miles. When you get home, the speedometer reads 5,208 miles. With only this information what value could you calculate?
O Velocity
O Displacement
O Acceleration
O Distance
Answers
Answer:
O Distance
Explanation:
With the given information, it is possible to find the distance of the car has traveled on the home from school.
This is possible because distance is the length of path a body covers.
From the given values:
Distance = 5208 - 5200 = 8miles
It is not possible to find the displacement because no direction was given.
Also velocity is not possible since the time frame of travel was not state.

What is Rutherford's model?Rutherford's model of atoms described the atom as a tiny, dense, positively charged core particle which is called a nucleus, in which nearly all the mass of the atom is concentrated, around within the nucleus which the light, negative constituents, called electrons, circulate at some specific distance, much like the planets which are revolving around the Sun.
