The right response is travelling to the Himalayan Mountains to see Uncle Chrissy gravitational.
Objects with mass produce a force called gravity that affects other mass-containing objects. Our planet has a gravitational field, and objects can be affected by that field's force.
The Arctic Ocean's surface has the highest gravitational acceleration, at 9.8337 m/s2, while Mount Nevado Huascarán in Peru has the lowest, at 9.7639 m/s2.
This indicates that the Earth's gravity is 9.789 m/s2 at the equator and 9.832 m/s2 at the poles. In other words, this centripetal force causes you to weigh slightly more at the poles than you do at the equator. The size of an object has an impact on gravity, as does

The equation below shows a general equation for a reaction, and the amounts of the substance are written underneath.
AB + CD → AC + BD
(15 g) (?) (?) (10 g)
The total mass of the products is 50g. Which best completes the other two amounts?
The amount of CD is 40 g, and the amount of AC is 35 g.
The amount of CD is 35 g, and the amount of AC is 40 g.
The amount of CD and AC would be the same.
The amount of CD and AC is undetermined.
Explanation:
The amount of CD is 35 g, and the amount of AC is 40 g.
Explanation:
AB + CD \rightarrow AC + BDAB+CD→AC+BD
The law of conservation of mass states that in any chemical reaction, the total mass of the reactants must be equal to the total mass of the products.
In this reaction, we know the mass of one reactant (AB, 15 g) and the mass of one product (BD, 10 g). In order to have the same total mass on the left side and on the right side of the equation, the mass of AC must be 5 g more than the mass of CD. We see that the only choice that satisfies this condition is:
The amount of CD is 35 g, and the amount of AC is 40 g.
In fact, if we assume these masses are correct, we have:
- on the reactant side: m(AB)+m(CD)= 15g + 35g = 50g
- on the product side: m(AC)+m(BD)= 40g + 10g = 50g
so, we have the same mass on both sides of the equation, and the law of conservation of mass is satisfied.
Answer:
B is the answer on edge
Explanation:
B: The amount of CD is 35 g, and the amount of AC is 40 g.
Which describes the motion in a convection current? horizontal motion only vertical motion only linear motion circular motion
Answer:
circular motion
Explanation:
Circular motion can be regarded as
movement of particular object along the circumference in a circle. It is
rotation of particular object along a circular path. Circular motion could be
uniform, along with constant angular rate of rotation as well as constant speed. It could also be non-uniform along with changing rate of rotation. The acceleration that is been experienced when one is in uniform circular motion is called"Centripetal acceleration"

A 12.0 volt battery is connected in a series to 4 identical 5.00 ohm resistors connected in parallel to each other. What is the current through the battery?
Answer:
9.6 Amperes
Explanation:
since the resistors are connected in parallel connection the equivalent resistance is1/R = 1 /5 + 1/5 + 1/5 + 1/5
solving for R we get 5/4 ohms
then from V=IR
I = V/R
I=12/(5/4)
hence I= 9.6 Amperes
A 12.0-volt battery is connected in a series, then the current through the battery is 9.6 A.
What are Resistors?Electrical resistance is implemented as a circuit element by resistors, which are passive two-terminal electrical components. Resistors are devices that are used in electronic circuits for a variety of purposes, including lowering current flow, adjusting signal levels, dividing voltages, biasing active components, and terminating transmission lines.
As part of motor controllers, power distribution systems, or as test loads for generators, high-power resistors that can dissipate many watts of electrical energy as heat may be used.

An object has a weight of 1550N when it is on the surface of a planet of radius R. What will be the gravitational force on the object after it has been moved to a distance of 4R from the surface of the planet?
Answer:
W = 96.875 N
Explanation:
For this exercise let's use the law of universal gravitation
F = [tex]G \frac{m M }{r^2}[/tex]
we substitute this force in Newton's second law
F = m a
G \frac{m M }{r^2} = m a
a = [tex]G \frac{M}{r^2}[/tex]
This sidewalk we will call it gravity acceleration
g₀ = a
the weight of a body is
W₀ = m g₀
if we change the cario of r ’= 4r
a’= [tex]G \frac{M}{r'^2 }[/tex]
a ’= G \frac{M}{(4r)^2 }
a' = [tex]G \frac{M}{r^2} \ \frac{1}{16}[/tex]
a ’= [tex]\frac{g_o}{16}[/tex]
therefore the weight of the body must be
W = m g = [tex]m \ \frac{g_o}{16}[/tex]
W = W₀ / 16
W = 1550/16
W = 96.875 N

Answer:
7 J
Explanation:
Given that,
A sphere is released into the atmosphere where air resistance is present.
The lose in energy is equal to 7 J
We need to find the gain in its kinetic energy.
We know that, as per the law of conservation of energy,
Loss in potential energy = gain in kinetic energy
⇒
Gain in kinetic energy = 7 J
Hence, the gain in kinetic energy is 7 J.

A proton travels through uniform magnetic and electric fields. The magnetic field is in the negative x direction and has a magnitude of 2.48 mT. At one instant the velocity of the proton is in the positive y direction and has a magnitude of 1840 m/s. At that instant, what is the magnitude of the net force acting on the proton if the electric field is (a) in the positive z direction and has a magnitude of 5.19 V/m, (b) in the negative z direction and has a magnitude of 5.19 V/m, and (c) in the positive x direction and has a magnitude of 5.19 V/m
Answer:
a) F = 15.6 10⁻¹⁹ k^ N, b) F = -1 10⁻¹⁹ k^ N,
c) F = (8.3 i^ + 73 k^) 10⁻¹⁹ N
Explanation:
In this exercise we calculate the magnetic and electric force separately.
Let's start by calculating the magnetic force
F_m = q v x B
where bold letters indicate vectors, the modulus of this expression is
F_m = q v B
the direction is given by the right hand rule, where the thumb points in the direction of velocity, the fingers are extended in the direction of the magnetic field and the palm is in the directional ne force if the charge is positive
let's calculate the magnitude
F_m = 1.6 10⁻¹⁹ 1840 2.48 10⁻³
F_m = 7.3 10⁻¹⁹ N
we calculate the direction, the thumb is in the direction of + y,
fingers extended in the direction of -ax
the palm remains + z
therefore the magnetic force is in the direction of the positive side of the z axis
The electric force is
F_e = q E
give several possibilities for the electric field
a) electric field E = 5.19 V / m in the direction of + z
we calculate
F_e = 1.6 10⁻¹⁹ 5.19
F_e = 8.3 10⁻¹⁹ N
the total force is
F = F_m + F_e
F = (8.3 k ^ + 7.3 k ^) 10⁻¹⁹
F = 15.6 10⁻¹⁹ k^ N
b) in the -z direction
F_e = -8.3 10⁻¹⁹ k^ N
F = Fm + Fe
F = (-8.3 k ^ + 7.3 k ^) 10⁻¹⁹
F = -1 10⁻¹⁹ k^ N
c) in the + x direction
F_e = 8.3 10⁻¹⁹ i^ N
the total force is
F = (8.3 i^ + 73 k^) 10⁻¹⁹ N

A hydrogen fuel cell vehicle is different from internal combustion engine as in fuel cell, hydrogen combines with oxygen whereas in internal combustion engines, gasoline is used.
What are hydrogen fuel cell vehicles and internal combustion engines?
In a internal combustion engine or fuel cell vehicle, the hydrogen fuel is combined with oxygen atom. While the combustion in a hydrogen- fuel or in a gasoline-powered engine is converted into mechanical energy, however in the hydrogen fuel cell vehicle, the chemical energy from the hydrogen and oxygen is converted into electrical energy.
Both hydrogen internal combustion engines and the hydrogen fuel cells can power vehicles using hydrogen, a zero-carbon fuel. Hydrogen engines burn hydrogen gas in an internal combustion engine, in the same way as the gasoline is used in a power engine.
