How are igneous rocks formed?
They are formed from cooled magma.
They are hot magma the moment it is expelled from a volcano.
They are formed over many years of pressure and heat within Earth.
They are formed from sediments that collected in ocean beds.
Answer:
What are igneous rocks?
Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies

A hose, of radius 0.018 m, is connected to a water faucet. The water pressure at the point where the hose connects to the faucet is 150,000 Pa. The other end of the hose is connected to an outlet of radius 0.011 m, where the water comes out. The total length of the hose and outlet is 15 m.
(a) An experiment shows that the water exists the outlet with a speed 5.2 m/s. What is the flow rate through the hose?
(b) What is the maximum height that the end of the outlet can he held above the faucet, and water still comes out?
(c) Suppose there is a small hole in the hose. How does that affect the speed at which the water comes out? Explain.
Explain each step!
Answer:
The smaller the hole, the more force.
The magnetic field strength in an experiment is 5.0 x 10–4 Newtons per Amp meter (or 5.0 x 10–4 N A–1m–1), where the unit of force is the Newton (N = kg m s–2) and the unit of current is the Ampere (A = C s–1). A Coulomb, C, is a unit of charge. The electric field strength in another experiment is 1.8 x 104 N C–1. From these parameters, both the magnetic displacement and the electric displacement were each measured to be 6.0 cm. Calculate the velocity of the particles.
Answer:
The velocity of the particles is "0.36×10⁸ m/s".
Explanation:
The given values are:
Magnetic field strength,
B = 5.0×10⁻⁴ N/Amp
In another experiment,
F = 1.8×10⁴
By considering the Lorentz force, the velocity will be:
⇒ [tex]qE=qvB[/tex]
then,
⇒ [tex]v=\frac{F}{B}[/tex]
On substituting the given values, we get
⇒ [tex]=\frac{1.8\times 10^4}{5.0\times 10^{-4}}[/tex]
⇒ [tex]=0.36\times 10^8 \ m/s[/tex]

Suppose the equation of the velocity of a car at any given time is Vx= 30m/s+(2.5m/s^3)t^2 Find the change in the velocity of the car during time t1= 4s and t2= 5.5s (a) 70.00 m/s (b) 105.63 m/s (c) 35.63 m/s (d) 175.63 m/s
Answer:
time=4, answer choice A
time=5.5, answer choice B
Explanation:
This is taken from the kinematic equation, v=vo+(1/2)at^2
Velocity at time 4 = 30+(2.5)(4)^2
Velocity at time 5.5 = 30+(2.5)(5.5)^2
Velocity at time 4 seconds = 70 m/s
Velocity at time 5.5 seconds = 105.63 m/s

8A

Answer:
700ma
Explanation:
all u do is have to add them up.
Ohm's law allows us to calculate the result for the value of the current when we change the resistance of the circuit:
The current is: i = 8 A
Ohm's law establishes that voltage is proportional to current and we call the constant of proportionality resistance in a circuit.
V = i R
Where V is the voltage, i the current and R the resistance of the circuit.
They indicate that the source supplies a current of i = 200 mA = 0.200 A at a load of R = 2 kΩ = 2 10³ Ω
Let's find the source voltage.
V = 0.200 2 10³
v = 400 V
Now with this voltage let's find the current for the new load of R = 50 Ω
i = V / R
i = 400/50
i = 8 A
In conclusion using Ohm's law we can calculate the result for the value of the current when we change the resistance of the circuit is:
The current is: i = 8 A

3. A bus is moving at 25 m/s when the driver steps on the brakes and brings the bus to a stop in 3.0 seconds. What is the average acceleration of the bus while braking?
Answer:
-8.3 m/s²
Explanation:
The acceleration of an object is defined as the change in velocity over the change in time.
a = Δv/Δt a = (v - v₀)/tWe are given the velocity of the bus, 25 m/s, and the time it takes the bus to stop, 3.0 s.
We know that if the bus stops, its velocity must be 0 m/s. Therefore, we can use these numbers to substitute into the acceleration formula.
a = (25 - 0)/3.0 a = 25/3 a = 8.33333333...The magnitude of the average acceleration of the bus while braking is 8.3 m/s².
However, in order for the bus to slow down and stop, the acceleration must have the opposite sign of the velocity.
This means that the acceleration is negative whilst the velocity is positive. So, the average acceleration of the bus while braking is -8.3 m/s².
2. Calculate the kinetic energy of a football being launched downfield by Patrick Mahomes. The football has a mass of .5 kg and is thrown at a velocity of 25 m/s. Find the kinetic energy.
Answer:
K.E = 156.25 Joules.
Explanation:
Given the following data;
Mass = 0.5kg
Velocity = 25 m/s
To find the kinetic energy;
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
[tex] K.E = \frac{1}{2}MV^{2}[/tex]
Where;
K.E represents kinetic energy measured in Joules.
M represents mass measured in kilograms.
V represents velocity measured in metres per seconds square.
Substituting into the equation, we have;
[tex] K.E = \frac{1}{2}0.5*25^{2}[/tex]
[tex] K.E = 0.25 * 625 [/tex]
K.E = 156.25 Joules.

You can use the curved part of a spoon as a mirror because it ________ light.
Which best completes the statement?
reflects
refracts
absorbs
enhances
Answer:
Reflects
Explanation:
A metal spoon looks very shiny because its surface is very smooth, which is why it acts like a mirror and reflects light very well.
You can use the curved part of the spoon as a mirror because it reflects light. Thus, the correct option is A.
What is reflection of light?Reflection is the phenomena of light, when the ray of light bounces off an object. If the surface is smooth and shiny, just like a glass, water or polished metal surface, the light will reflect at the same angle as it hit the surface of the object. This is called as specular reflection.
The laws of reflection states that the incident ray, the reflected ray, and the normal ray all lie at the same point of incidence, and lie in the same plane of the surface. And, the angle of incidence is equal to the angle of reflection of light.
Therefore, the correct option is A.

HELPPP BESTIESSS An astronomer is studying two stars that have about the same size and brightness. From the Earth, one of the stars appears very bright in the night sky. The other star appears very faint and dim.
Why does one star appear to be brighter than the other?
A. The Earth is moving toward the brighter star.
B. The Earth is moving toward the dimmer star.
C. The Earth is farther from the brighter star.
D. The Earth is closer to the brighter star.
Answer:
If the stars are about the same size and brightness then the earth must be nearer to the stat that appears brighter, The stars movement, nearer or farther, would only effect the frequency received (redshift).
Answer:
D- The earth is closer to the bright star
Explanation:
If two stars have SAME brightness and size then that means the only point of difference is distance . Earth should be closer to the brighter star for the star to be bright.

We are given:
Mass of the Crate(m) = 71 kg
Applied force(F) = 577 N
Resolving the applied force:
To solve this problem, we will first make a free-body diagram (attached)
The Applied force has been resolved into 2 components denoted by a thinner line and 'g' is the acceleration due to gravity
We found the values by using basic trigonometry
Finding the Normal Force:
Normal force is equal and opposite to the net force applied on the ground. So, we will subtract the vertical component of the applied force from the weight of the crate.
Normal force = mg - F*Sin(27°)
Normal force = [(71)*(9.8)] - [ (577)(0.454) ] [g = 9.8 m/s²]
Normal Force = 433.84 N
of 72.0 units. If the mass of Object 1 is halved AND the mass of object 2 is tripled, then the new gravitational force will be units.

Planet RMM-1 has a mass of 28,500 kg and the star it revolves around has
a mass of 2.20 x 10^8 kg. If the star emits a gravitational force of 39 N how
far away are the two objects from each other?
Gravitational force = G · (mass₁) · (mass₂) / (distance)
(distance²) = G · (mass₁) · (mass₂) / (Gravitational force)
G = 6.67 x 10⁻¹¹ n-m² / kg² (the "gravitational constant")
Distance² = (6.67 x 10⁻¹¹ n-m² / kg²) (28,500 kg) (2.2 x 10⁸ kg) / (39 N)
Distance² = (6.67 · 28,500 · 2.2 x 10⁻³ N-m²) / (39N)
Distance² = (418.209 N-m²) / (39N)
Distance² = 10.72 m²
Distance = 3.275 meters

Find the position of charge 3 when q = 10n C
Answer:
0.667 cm
Explanation:
|F_1on3| = |F_2on3|
k×q1×q3/x^2 = k×q2×q3/(d-x)^2
q1/x^2 = q2/(d-x)^2
(d-x)^2/x^2 = q2/q1
(d-x)/x = sqrt(q2/q1)
(2 - x)/x = sqrt(4×q/q)
(2 - x)/x = 2
2 - x = 2x
2 = 3x
x = 2/3
x= 0.667 cm
