Answer:D
Explanation:
The characteristic shared by extrusions, intrusions, and faults is all are younger than surrounding rocks.
The correct option is fourth.
What is extrusion?Extrusion is a process of extruding.
Intrusion is the process of intruding. The forced entry of molten rock or magma into two different rock formations. It is also the intruded magma.
The movement of magma over the surface of the Earth coming out through volcano craters and cracking in the earth's crust forms igneous rock.
The characteristic shared by extrusions, intrusions, and faults is all are younger than surrounding rocks.
The surrounding rocks are already present. After that the entry of magma occurs which forms new rock. So, in age surrounding rocks are older than the middle.
Thus, the correct option is fourth.

The speed needed to escape the pull of Earth's gravity is 11.3 km/s. What is this speed in mi/h? (1 mile = 1609 m)
Answer:
11.3 km/sec * 1000 m/km / 1609 m/mi = 7.02 mi / sec
7.02 mi/sec * 3600 sec / hr = 25,300 mph
The value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.
Given the following data;
Speed = 11.3 km/s1 mile = 1609 mIn this exercise, you're required to convert the value of the speed needed to escape the pull of Earth's gravity in kilometer per seconds (km/s) to miles per hour (mi/h).
Conversion:
1 mile = 1.609 kilometer
X mile = 11.3 kilometer
Cross-multiplying, we have;
[tex]1.609[/tex] × X = [tex]11.3[/tex]
[tex]X = \frac{11.3}{1.609}[/tex]
X = 7.0230 miles
Since we know that one (1) hour is equal to 3600 seconds, we would multiply the value of X by 3600 in order to convert it to miles per hour (mi/h).
X = 7.0230 × 3600
X = 25282.8 mi/h
Therefore, the value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.

Explanation:
a tungsten and coil has a resistance of 12 ohm at 15 degree celsius is the temperature coefficient of resistance of tungsten is 0.004 calculate the equal resistance at 80 degree Celsius
Answer:
The resistance of the tungsten coil at 80 degrees Celsius is 15.12 ohm
Explanation:
The given parameters are;
The resistance of the tungsten coil at 15 degrees Celsius = 12 ohm
The temperature coefficient of resistance of tungsten = 0.004/°C
The resistance of the tungsten coil at 80 degrees Celsius is found using the following relation;
R₂ = R₁·[1 + α·(t₂ - t₁)]
Where;
R₁ = The resistance at the initial temperature = 12 ohm
R₂ = The resistance of tungsten at the final temperature
t₁ = The initial temperature = 15 degrees Celsius
t₂ = The final temperature = 80 degrees Celsius
α = temperature coefficient of resistance of tungsten = 0.004/°C
Therefore, we have;
R₂ = 12×[1 + 0.004×(80 - 15)] = 15.12 ohm
The resistance of the tungsten coil at 80 degrees Celsius = 15.12 ohm.

C.) 90 kg
Explanation:
A.) If Justin races his Chevy S-10 down highway 37 north for 2,560 meters in 60 seconds, what is his velocity?
Velocity = displacement/time
Velocity = 2560/60
Velocity = 42.67 m/s
B.) The Chevy S-10 started rounding at 10 meters per hour. What is the acceleration at 30 seconds on the highway?
Acceleration = velocity/time
Acceleration = 10/30
Acceleration = 0.33 m/s^2

27 miles per gallon into kilometers per liter.
Answer:
11.479 kilometres per litre
Explanation:
for an approximate result, divide the fuel economy value by 2.352
27 miles per gallon is equivalent to approximately 6.09 kilometers per liter.
What is Unit conversion?A statement of the connection between units that are used to alter the units of a measured quantity without affecting the value is called a conversion factor. A conversion ratio (or unit factor), if the numerator and denominator have the same value represented in various units, always equals one (1).
To convert 27 miles per gallon to kilometers per liter, we need to use conversion factors:
1 mile = 1.60934 kilometers
1 gallon = 3.78541 liters
So, first we convert miles to kilometers:
27 miles * 1.60934 km/mile = 43.45218 kilometers
Then we convert gallons to liters:
1 gallon = 3.78541 liters
27 miles per gallon = 27 miles / 1 gallon = 27 / 3.78541 liters/mile = 7.13888 liters/kilometer
Finally, we divide the distance traveled in kilometers by the amount of fuel used in liters:
43.45218 km / 7.13888 liters = 6.09023 kilometers per liter
Therefore, 27 miles per gallon is equivalent to approximately 6.09 kilometers per liter.

A biker goes out for a ride and begins riding North at 18 km/h for 200 minutes, then the driver turns around and rides at 12 km/h South for another 50 minutes.
Answer:
Explanation:
18 km / h
= 300 m / min
12 km / h = 200 m / min
distance travelled in 200 minutes = 300 x 200 = 60000 m
distance travelled in 50 minute in return journey = 200 x 50 = 10000 m
total distance travelled = 70000 m
total time = 250 minute
speed = 70000 / 250
= 280 m / min
= 16.8 km / h
Total displacement = 60000 - 10000 = 50000 m
total time = 250 min
velocity = 50000 / 250
= 200 m / min
= 12 km / h

an elastic material of length 3m is to be stretched to produce an extension three times it's original length. Calculate the force required to produce the extension if the force constant of the material is 982.3 Newton per metre
Answer:
F = 8840.7 N
Explanation:
The parameters given are:
Length L = 3 metres
Extension e = 3 × 3 = 9m
Force constant K = 982.3 Newton per metre
From Hook's law,
Provided the elastic limit is not extended, the extension is directly proportional to the force applied.

what volume will a sample of copper 98.2 g occupy? the density of copper is 8.96 g/mL
Answer:
Density=mass/volume.
8.96=98.2/volume.
volume=98.2/8.96=10.95982143 ~ 11cm^3.
The volume of a sample of copper of 98.2 g would be 10.95 ml if the density of copper is 8.96 g/mL.
What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
Due to their superior electrical and thermal conductivities, remarkable resistance to corrosion, and simplicity of production, copper alloys are frequently employed. In general, copper alloys are not magnetic. Electrical wire, cable, contacts, and other components.
As given in the problem the density of copper is 8.96 g/mL, and we have to find the volume occupied by the sample of copper.
mass = density×volume
98.2 g = 8.96 g/mL×volume
volume =98.2/8.96
=10.95 ml
Thus, the volume of a 98.2 g sample of copper would be 10.95 ml.

Answer:
A.) r = 2t
B.) V = 33.5t^3
Explanation:
Given that a spherical balloon is being inflated and the radius of the balloon is increasing at a rate of 2 cm/s
A) Express the radius (r) of the balloon as a function of the time (t).
Since the rate = 2 cm/s that is,
Rate = radius/ time
Therefore,
2 = r/t
Make r the subject of formula
r = 2t
(B) If V is the volume of the balloon as a function of the radius, find V or and interpret it.
Let assume that the balloon is spherical. Volume of a sphere is;
V = 4/3πr^3
Substitute r = 2t into the formula
V = 4/3π(2t)^3
V = 4/3π × 8t^3
V = 32/3 × πt^3
V = 33.5t^3

a marble is shot horizontally from a table .8 m High, and it lands, 1.2 meters away horizontally. what was the initial velocity of the marble as it left the table
Answer:
3 m/s
Explanation:
First, find the time it takes to land.
Given in the y direction:
Δy = 0.8 m
v₀ = 0 m/s
a = 10 m/s²
Find: t
Δy = v₀ t + ½ at²
0.8 m = (0 m/s) t + ½ (10 m/s²) t²
t = 0.4 s
Next, find the velocity needed to travel 1.2 m in that time.
Given in the x direction:
Δx = 1.2 m
a = 0 m/s²
t = 0.4 s
Find: v₀
Δx = v₀ t + ½ at²
1.2 m = v₀ (0.4 s) + ½ (0 m/s²) (0.4 s)²
v₀ = 3 m/s
