If a circuit has a current of 0.25 A and a voltage of 3 V, how much resistance is in the circuit? A 0.083 ohms B 0.75 ohms C 1.5 ohms D 12 ohms
Answer:
The resistance in the circuit is 12 ohm.
(D) is correct option
Explanation:
Given that,
Current = 0.25 A
Voltage = 3 V
We need to calculate the resistance
Using ohm's law
[tex]V=IR[/tex]
[tex]R=\dfrac{V}{I}[/tex]
Where, V = voltage
I = current
R = resistance
Put the value into the formula
[tex]R =\dfrac{3}{0.25}[/tex]
[tex]R=12\ ohm[/tex]
Hence, The resistance in the circuit is 12 ohm.
(D) is correct option
If a sled is being pulling on the ground toward the right with a force of 100 N and friction is acting on it to the left with a force of 85 N, what is the net force
of the sled?
O 15 N to the left
15 N to the right
185 N to the right
185 N to the left
Answer:
15 N to the right.
Explanation:
100 N to the right -->
85 N to the left <--
So therefore in order to find the net force of where the sled is being dragged towards is 100 N - 85 N = 15 N.
So the sled is moving towards the right of 15 N.

Does the moon control the waves in the ocean?
Answer:
no don't think so
Explanation:
JESUS CHRIST controls everything 100IQ
No, the moon does not directly control the waves in the ocean. The primary factors that influence the formation of waves in the ocean are wind and the interaction between wind and the water's surface.
The moon, however, does play a significant role in influencing the tides, which are the periodic rise and fall of the ocean's surface.
The gravitational force exerted by the moon, as well as the sun to a lesser extent, creates tidal bulges on the Earth. As the Earth rotates, these tidal bulges move around the planet, resulting in the daily cycle of high tides and low tides.
The gravitational pull of the moon is stronger on the side of the Earth facing the moon, causing a high tide, while on the opposite side, a high tide also occurs due to the centrifugal force resulting from the Earth's rotation. The areas in between experience low tides.
While tides can affect the height and intensity of ocean waves near the coastlines, the actual formation and behavior of waves are primarily driven by wind patterns, water depth, and other factors such as underwater topography.
Waves are generated when the wind transfers its energy to the water's surface, creating oscillations that propagate as waves. These waves can travel vast distances across the ocean, even in the absence of tidal influences.
In conclusion, while the moon's gravitational pull influences the tides, it does not directly control or generate the waves in the ocean.
Waves are primarily driven by wind and other factors, whereas tides are the result of gravitational forces acting on the Earth's oceans.

"A car is travelling at 70 m/s. The driver sees a cow in the road and slows down with a constant acceleration for 10 seconds before coming to a stop. What is the car’s displacement by the time is stops." what information do you know?
The question does not ask for anything in particular. I will calculate the acceleration and distance.
Answer:
The acceleration of the car is [tex]-7\ m/s^2[/tex]
The distance traveled before stopping is 350 m
Explanation:
Constant Acceleration Motion
It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.
Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:
[tex]v_f=v_o+at\qquad [1][/tex]
The distance traveled by the object is given by:
[tex]\displaystyle x=v_o.t+\frac{a.t^2}{2}\qquad [2][/tex]
The car has an initial speed of v0=70 m/s when the driver sees a cow in the road and steps on the brakes with an (assumed) constant acceleration during t=10 seconds before stopping (vf=0).
With the information provided, we can calculate the value of the acceleration and the distance traveled.
Using the equation [1] we can solve for a:
[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]
Substituting the numerical values:
[tex]\displaystyle a=\frac{0-70}{10}=-7\ m/s^2[/tex]
The acceleration of the car is [tex]-7\ m/s^2[/tex]
The distance is now calculated by using [2]
[tex]\displaystyle x=70\cdot 10+\frac{(-7)\cdot 10^2}{2}[/tex]
[tex]\displaystyle x=700-\frac{700}{2}=350\ m[/tex]
The distance traveled before stopping is 350 m

What is symbiosis
A an interaction between organisms
B a type of reproduction
C and organelle in the cell
D a process by which plants make their own food
Answer:
A an interaction between organisms
Explanation:
Symbiosis is an interaction between two or more organisms. It is a biological interaction which can be mutualism, commensalism or parasitic.
Mutualism is a form of interaction between two organisms where they both derive benefit from one another. Commensalism is an interaction in which one organism derives benefit and the other is neutral. Parasitic is an interaction where an organism derives benefit from the other in which the other is harmed.Symbiosis simply entails the interactions between organisms.

6. A child tugs on a rope attached to a 0.62-kg toy with a horizontal force
of 16.3 N. A puppy pulls the toy in the opposite direction with a force 15.8
N.What is the acceleration of the toy? (Hint: Remember direction:
towards child or puppy?)
Answer:
Explanation:
Force Mass * acceleration
F = ma
a = F/m
Sum of force = 16.3N - 15.8N = 0.5N
Mass = 0.62kg
Substitute
a = 0.5/ * 0.62
a = 0.81m/s²
The acceleration of the toy is 0.81m/s²

If your mass is 63.7 kg, and you are standing 7.5 m away from a boulder with
a mass of 9,750.6 kg, what is the gravitational force between you and the
boulder? Newton's law of gravitation is F gravity
Gm; m2. The gravitational
constant G is 6.67 x 10-11 Nm2/kg?
7.36 × 10⁻⁷ Newton is the gravitational force between you and the boulder.
What is Gravity ?Gravity or gravitational force of the earth is defined as the force on which a planet attracts or pulls another planet towards the center. It is represented by symbol g.
What is Force ?Force is defined as the physical quantity and the vector quantity which acts on an object and causes the object to change its size and shape to stop moving and start moving to decelerate and accelerate. Force has both the directions as well as magnitude. The SI unit of force Newton which is also represented as N, named the scientist Sir Issac Newton.
What is Newton's Law of universal gravitational ?The Newton's Law of universal gravitational is defined as the universal force of attraction acting between the two bodies which is inversely proportional to the square of the distance between them and the directly proportional to the product of their masses.
It is represented as
[tex]F = \frac{G m_1 m_2}{r^2}[/tex]
Where,
F represents the gravitation force between the two bodies
G represents the gravitation constant
m₁ represents the first body mass
m₂ represents the second body mass
r represents the distance between the two bodies.
Here,
G = 6.67 x 10-¹¹ Nm²/kg
m₁ = 63.7 kg
m₂ = 9,750.6 kg
r = 7.5 m
Now by putting in the above formula we get the gravitational force between you and the boulder.
[tex]F = \frac{6.67 \times 10^{-11}\ Nm^2/kg \times 63.7\ kg \times 9,750.6\ kg}{(7.5 m)^2}[/tex]
[tex]F = \frac{4142825.1774 \times 10^{-11}\ Nm^2/kg}{56.25}[/tex]

A ball is dropped off the roof of a tall building. If the ball reaches the ground in 8 seconds, how tall is the building, in meters? Round to the nearest whole number (a=9.8 m/s2)
Let b be the height of the building, and y the height of the ball at time t, given by
y = b - 1/2 gt²
where g = 9.8 m/s² is the magnitude of the acceleration due to gravity.
It takes the ball 8 s to reach the ground, at which point y = 0, so that
0 = b - 1/2 (9.8 m/s²) (8 s)²
b = 1/2 (9.8 m/s²) (8 s)²
