Answer:
a) 60kg
Explanation:
mass is not affected by gravity
The mass of Joe on the moon is approximately 60 kg. Hence, option (a) is correct.
Given data:
The weight of Joe is, W = 600 N.
The weight of any object is the product of mass and gravitational acceleration of an object. It is the expressed as,
W = mg
Here,
m is the mass of Joe.
g is the gravitational acceleration.
Solving as,
W = mg
600 = m × 10
m = 60 kg.
Thus, we can conclude that the mass of Joe on the moon is approximately 60 kg. Hence, option (a) is correct.

Explanation:
Calcula la fuerza magnética de una carga que se desplaza hacia la derecha con una velocidad de 5 X 10 a la 6 metros sobre segundo. Que forma un campo magnético de 0.8 Teslas. Recuerda que la carga de un electrón es de 1.602 X 10 a la menos 19 [Coulombs]
Answer:
La fuerza magnética del electrón es 6.41x10⁻¹³ N.
Explanation:
Podemos encontrar la fuerza magnética (F) usando la ley de Lorentz:
[tex] F = qv\times B [/tex]
En donde:
q: es la carga del electrón = 1.602x10⁻¹⁹ C
v: es la velocidad del electrón = 5x10⁶ m/s
B: es el campo magnético = 0.8 T
[tex] F = qv\times B = 1.602 \cdot 10^{-19} C*5\cdot 10^{6} m/s*0.8 T = 6.41 \cdot 10^{-13} N [/tex]
Por lo tanto, la fuerza magnética del electrón es 6.41x10⁻¹³ N.

How much force (newtons) is required to accelerate a 2.55 kg remote-controlled toy car at a rate of 6.00 m/s2
Answer:
15.3 N
Explanation:
Force = mass x acceleration
= 2.55 kg x 6.00 m/s^2
= 15.3 kgm/s^2 = 15.3 N
The required force to accelerate a 2.55 kg remote-controlled toy car at a rate of 6.00 m/s^2 be 15.3 N.
What is force?The definition of force in physics is: The push or pull on a mass-containing item changes its velocity.
An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force.
Given parameters:
Mass of the remote-controlled toy car : m = 2.55 kg.
Acceleration of the remote-controlled toy car :a = 6.00 m/s^2
Now according to Newton's 2nd law of motion,
Force = mass x acceleration
= 2.55 kg x 6.00 m/s^2
= 15.3 kgm/s^2
= 15.3 N
Hence, required force is 15.3 N.

1. What are valence electrons used for by an element?
Answer:
An element's valence electron tells us about its ability to react and not react. More rules to this, but that's the gist of it. it also helps us form bonds
Explanation:
Valence electrons are used by an element for bonding and ionization, contributing to the element's chemical reactivity and behavior.
Valence electrons also play a vital role in ionization, which refers to the process of gaining or losing electrons to form ions. Elements tend to gain or lose electrons in order to achieve a stable electron configuration, typically by acquiring a full valence shell.
Metals, located on the left side of the periodic table, have fewer valence electrons, often one or two, and tend to lose them to form positive ions (cations). This characteristic makes them good conductors of electricity.
Nonmetals, located on the right side of the periodic table, have a nearly full valence shell and tend to gain electrons to achieve a stable configuration, forming negative ions (anions). Nonmetals generally do not conduct electricity as well as metals.
In summary, valence electrons are used by an element for bonding, where they participate in the formation of covalent and ionic bonds, and for ionization, where they are gained or lost to form ions and achieve a stable electron configuration.

Tap the point on this graph where the ball has the greatest Kinetic Energy if it were to move from Point A to G. Target Image
I don't understand the question
Answer:
As the ball falls from C to E, potential energy is converted to kinetic energy. The velocity of the ball increases as it falls, which means that the ball attains its greatest velocity, and thus its greatest kinetic energy, at E. 19.

A football is thrown with a horizontal velocity of 15.0 m/s and a vertical velocity of 4.25m/s. What is the football's velocity?
3. An airplane is heading north with an airspeed of 325 m/s with a wind from the east at 55.0 m/s. What is the airplane's velocity relative to the ground? Is the airplane's ground speed faster or slowerthan its air speed? Why?
Let a denote the airplane's velocity in the air, g its velocity on the ground, and w the velocity of the wind. (Note that these are vectors.) Then
a = g + w
and we're given
a = (325 m/s) j
w = (55.0 m/s) i
Then
g = - (55.0 m/s) i + (325 m/s) j
The ground speed is the magnitude of this vector:
||g|| = √[ (-55.0 m/s)² + (325 m/s)² ] ≈ 330. m/s
which is faster than the air speed, which is ||a|| = 325 m/s.
The relative velocity of the airplane with respect to the ground is 329.6 m/s.
The airplane's ground speed is faster than the airspeed because the relative speed of the the ground is zero causing the airplane to appear faster.
The given parameters;
speed of the airplane, [tex]V_P[/tex] = 325 m/s northspeed of the wind, [tex]V_w[/tex] = 55 m/s eastThe velocity of the airplane relative to the ground is calculated by applying Pythagoras theorem as follows;
[tex]V_G_P^2 = 325^2 + 55^2\\\\V_G_P = \sqrt{325^2 + 55^2} \\\\V_G_P = 329.6 \ m/s[/tex]
Thus, we can conclude that the airplane's ground speed is faster than the airspeed because the relative speed of the the ground is zero causing the airplane to appear faster.
