Form hypothesis: How do you think increasing the resistance in a circuit will affect the current in the wire? (format: if, then, because)
Answer:it would make it thicker
Explanation:
Answer:
"The equation shows that the current in a circuit is inversely proportional to the resistance of the circuit. An increase in resistance would result in a decrease in current. And the factor by which the resistance increases is the same factor by which the current decreases."
Explanation:
Because it's just like wearing a glove/mitten when getting something out of the oven, because of the insulation from the glove/mitten, it reduces the heat that gets through into your hand, and it protects it. Just like what the "answer" says, it said that the resistance would decrease current.

Thor deja caer su martillo de la torre Torre Stark que tiene 95 pisos, si al llegar el Mjolnir al piso han transcurrido 9.5 segundos. Determina: a) La velocidad con la que el Mjonir golpea el suelo
Answer:
La magnitud de la velocidad con la que Mjonir golpea el suelo es 93.2 m/s.
Explanation:
Podemos encontrar la velocidad con la que el martillo golpea el suelo usando la siguiente ecuación:
[tex] v_{f} = v_{0} - gt [/tex] (1)
En donde:
[tex] v_{f}[/tex]: es la velocidad final =?
[tex] v_{0}[/tex]: es la velocidad inicial = 0 (lo deja caer)
g: es la gravedad = 9.81 m/s²
t: es el tiempo = 9.5 s
Al reemplazar los valores anteriores en la ecuación (1), tenemos:
[tex] v_{f} = 0 - 9.81 m/s^{2}*9.5 s = -93.2 m/s [/tex]
El signo negativo se debe a que el vector velocidad está dirigido hacia abajo en el eje vertical (y).
Por lo tanto, la magnitud de la velocidad con la que Mjonir golpea el suelo es 93.2 m/s.

How much does a 20 kg rock weigh on Earth where g = 9.8 m/s2?
Answer:
[tex]\huge\boxed{196\:N}[/tex]
Explanation:
Mass and weight ain't the same thing. So, for calculating weight we would use Newton's 2nd Law of Motion i.e. Force = Mass × Acceleration.
According to question,
The mass is 20kg
Acceleration is 9.8 m/s^2
Putting the given values into the formula,
F = 20 × 9.8
F = 196N
So, the weight of the rock is 196 N

What is reflection of light and its laws ?
Answer:
So, put simply, reflection is light bouncing off surfaces. The law of reflection determines how the light bounces off a surface. The law of reflection states that the angle of incidence is equal to the angle of reflection.
Hope this helps..The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray. (By convention, all angles in geometrical optics are measured with respect to the normal to the surface that is, to a line perpendicular to the surface.

You are trying to climb a castle wall so, from the ground, you throw a hook with a rope attached to it at 24.1 m/s at an angle of 65.0° above the horizontal. If it hits the top of the wall at a speed of 16.3 m/s, how high is the wall?
Answer:
The value is [tex]h = 13.2 \ m[/tex]
Explanation:
From the question we are told that
The speed of the rope with hook is [tex]u = 24 .1 \ m/s[/tex]
The angle is [tex]\theta = 65.0^o[/tex]
The speed at which it hits top of the wall is [tex]v = 16.3 m/s[/tex]
Generally from kinematic equation we have that
[tex]v_y^2 = u_y ^2 + * 2 (-g)* h[/tex]
Here h is the height of the wall so
[tex][16.3 sin (65)]^2 = [24.1 sin (65)] ^2+ 2 (-9.8)* h[/tex]
=> [tex]h = 13.2 \ m[/tex]

48.3 m/s
-68.4 m/s
84.7 m/s
-57.6 m/s
Answer:
a= g = - 9.81 m/s2.
The following equations will be helpful:
a = (vf - vo)/t d = vot + 1/2 at2 vf2 = vo2 + 2ad
When you substitute the specific acceleration due to gravity (g), the equations are as follows:
g = (vf - vo)/t d = vot + 1/2 gt2 vf2 = vo2 + 2gd
If the object is dropped from rest, the initial velocity ("vi") is zero. This further simplifies the equations to these:
g = vf /t d = 1/2 gt2 vf2 = 2gd
The sign convention that we will use for direction is this: "down" is the negative direction. If you are given a velocity such as -5.0 m/s, we will assume that the direction of the velocity vector is down. Also if you are told that an object falls with a velocity of 5.0 m/s, you would substitute -5.0 m/s in your equations. The sign convention would also apply to the acceleration due to gravity as shown above. The direction of the acceleration vector is down (-9.81 m/s2) because the gravitational force causing the acceleration is directed downward.

Which is the correct equation for the force applied by a spring?
Answer:
B. [tex]F = -k*x[/tex]
Explanation:
The force of a spring can be easily calculated using Hooke's law which tells us that the force applied on a spring is equal to the product of the constant of a spring by the compressed or stretched distance of the spring.
That is:
[tex]F = k*x[/tex]
k = spring constant [N/m]
x = distance [m]
When you walk across the ground and push on it with your feet...
Group of answer choices
The ground pushes back more strongly than your feet
The ground pushes back on your feet with equal force
There is no effect on the ground
The ground pushes back less strongly than your feet
Answer:
The ground pushes back on your feet with equal force
Explanation:
When you walk across the ground and push on it with your feet, the ground pushes back on your feet with an equal and opposite force.
This interpretation and knowledge is gotten from Newton's third law of motion.
It states that "action and reaction force are equal and opposite in nature".
The force applied to a body responds with an opposite force in the other direction. Therefore, the reaction force is of equal magnitude but directed in another direction.Answer:
the answer is the second one: the ground pushes back on your feet with equal force

A student buys a plastic dart gun and tries to find the maximum horizontal range. The student shoots the gun straight up and it takes 3.7 seconds for the dart to return back to the height of the barrel. What is the maximum horizontal range of the gun?
Answer:
The value is [tex]R_{max} = 33.54 \ m[/tex]
Explanation:
From the question we are told that
The total time of flight is [tex]t = 3.7 \ s[/tex]
Generally from kinematic equation
[tex]v = u - g * \frac{t}{2}[/tex]
So v is the velocity at maximum height and the value is v = 0 m/s
So
[tex]0 = u - 9.8 * \frac{ 3.7}{2}[/tex]
=> [tex]u = 18.13 \ m/s[/tex]
Here u is the initial velocity of the dart as it leaves that gun
Gnerally the horizontal range of the dart is mathematically represented as
[tex]R = \frac{u ^2 sin 2\theta }{g}[/tex]
For maximum horizontal range the value of [tex]\theta = 45^o[/tex]
So
[tex]R_{max} = \frac{ 18.13 ^2 sin 2(45) }{9.8}[/tex]
=> [tex]R_{max} = 33.54 \ m[/tex]
A gun fires a bullet horizontally with a velocity of 90 m/s from a tower. Neglecting air resistance, how far will the bullet travel horizontally in 4 seconds?
Answer:
The distance covered along the horizontal axis is [tex]s = 360 \ m[/tex]
The distance covered along the vertical axis is [tex]h = 78.4 \ m[/tex]
Explanation:
From the question we are told that
The horizontal velocity is [tex]u_x = 90 \ m/s[/tex]
The time considered is [tex]t = 4 \ s[/tex]
Generally the distance which the bullet will cover in the horizontal direction for the given time is mathematically represented as
[tex]s = u_xt + \frac{1}{2}* at^2[/tex]
Here a is the acceleration along the horizontal direction and the value is [tex]a = 0 \ m/s^2[/tex]
So
[tex]s = 90 * 4 + \frac{1}{2}* * 0 * 4^2[/tex]
=> [tex]s = 360 \ m[/tex]
Generally the distance which the bullet will cover in the vertical direction for the given time is mathematically represented as
[tex]h= u_y t + \frac{1}{2}* gt^2[/tex]
Here [tex]u_y[/tex] is the initial velocity of the bullet along the vertical axis and the value is [tex]u_y = 0 \ m/s[/tex]
[tex]h = 0 * 4 + \frac{1}{2}* 9.8 *4^2[/tex]
=> [tex]h = 78.4 \ m[/tex]
