Determine the forces in all the members and state if these members are in tension or compression,use table to arrange your calculations (show the results on the truss)
Answers
To determine the forces in all the members, we have to consider as follows:
1. Draw the truss and label all the members and joints.
2. Determine the support reactions by solving the equilibrium equations (sum of vertical forces, horizontal forces, and moments should be zero).
3. Using the Method of Joints or Method of Sections, analyze each joint or section by applying the equilibrium equations.
4. For each member, calculate the force and determine if it is in tension or compression based on the direction of the force acting on the member.
5. Organize your results in a table with columns for the member label, force value, and whether the force is tension or compression.
6. Finally, show the results on the truss by indicating the force magnitudes and whether each member is in tension or compression.
Remember that for a more accurate answer, I need more details about the truss you are analyzing.

Calculate in meters the distance between a galaxy and the Earth if the distance is equal to 7.2 light years.
Answers
Answer:
68.2 Quadrillion meters
Explanation:
A lightyear is the distance that light travels in one year.

One year has 31536000 seconds so , light covers
\(9.461*10^{15}\ meters\ in\ one\ year\)
so 7.2 light years is
\(7.2*(9.461*10^{15})\\6.82*10^{16}\)
so 7.2 light years is

Neglecting air pressure: find the pressure at a depth of 10m, 100m, 1000m and at the bottom of the ocean (2000 m.) Consider density of ocean water 1030kg/m3 and g = 10m/s2.
Answers
When we talk about pressure, it is essential to note that pressure is the force applied per unit area. The units for pressure are pascals (Pa). Here, we neglect air pressure.
We want to find the pressure at different depths of the ocean with a density of 1030 kg/m3 and gravity equal to 10m/s2. We can use the formula P = ρgh to calculate pressure, where P is pressure, ρ is the density, g is the gravitational acceleration, and h is the height or depth. Let us find the pressure at each given depth.1. Pressure at a depth of 10 m: Using the formula, we have:P = ρgh= (1030 kg/m³) × (10 m/s²) × (10 m)P = 1.03 × 10⁵ PaTherefore, the pressure at a depth of 10 m is 1.03 × 10⁵ Pa.2. Pressure at a depth of 100 m: Using the same formula, we have:P = ρgh= (1030 kg/m³) × (10 m/s²) × (100 m)P = 1.03 × 10⁶ PaTherefore, the pressure at a depth of 100 m is 1.03 × 10⁶ Pa.3. Pressure at a depth of 1000 m: Again, using the same formula, we have:P = ρgh= (1030 kg/m³) × (10 m/s²) × (1000 m)P = 1.03 × 10⁷ PaTherefore, the pressure at a depth of 1000 m is 1.03 × 10⁷ Pa.4. Pressure at the bottom of the ocean (2000 m): Lastly, we use the same formula:P = ρgh= (1030 kg/m³) × (10 m/s²) × (2000 m)P = 2.06 × 10⁷ PaTherefore, the pressure at the bottom of the ocean (2000 m) is 2.06 × 10⁷ Pa.

How long will it take light to travel from Earth to the moon if it is 386,400 km?
Answers
Answer:
The speed of light is approximately 299,792 kilometers per second. If the distance from Earth to the Moon is 386,400 kilometers, then it would take light about 1.28 seconds to travel from Earth to the Moon.
As a result, light would need to travel from Earth to the moon for around 1.29 seconds.
How much time does light take to get from Earth to the Moon?On average, our planet and its sizable natural satellite are separated by roughly 238,855 miles (384,400 kilometres). As a result, the total amount of moonlight we observe is 1.255 seconds old, and it takes around 2.51 seconds for light to travel from the Earth to the moon.
we can use the following formula:
time = distance / speed
First, we need to convert the distance from kilometers to meters:
386,400 km = 386,400,000 meters
Now, we can calculate the time it will take light to travel from Earth to the Moon:
time = 386,400,000 meters / 299,792,458 meters per second

[Specific of heat capacity of copper = 4.0× 10²J/kg-1/K ^-1. Please any Physics student can help or if you have any idea, you can help me out. Thanks.✨✨
Answers
Answer:
The final temperature is \(29.6^oC\).
Explanation:
When the two masses come in contact, one releases heat and the other absorbs it. The former can be modelled with the equation \(HeatLost = (Mass1 (kg))(c1)(T1-T)\), and the latter by \(HeatGained=(Mass2(kg))(c2)(T-T2)\)
m1=0.15 kg
m2=0.06 kg
T1 = 70 degrees Celsius = 343 K
T2 = 20 degrees Celsius = 293 K
T= Final temperature
c1 = Specific heat capacity of copper
c2 = Specific heat capacity of water
Because there is no heat lost into the surroundings, the heat removed from one substance is the same as the heat gained in the other. Therefore:
\((Mass1)(c1)(T1-T)=(Mass2)(c2)(T-T2)\)
\((0.150)(400)(343-T)=(0.06)(4184)(T-293)\)
\((60)(343-T)=(251.04)(T-293)\)
\(20580-60T=251.04T-73554.72\)
\(-311.04T=-94134.72\)
\(T=302.6 K\)
\(T=29.6^oC\)

Answers
F b = (m * v) / t is the formula for the amount of average net force needed to reach a specific velocity.
What is the average velocity's magnitude formula?Average speed is determined by dividing the total distance you travelled by the total time, whereas average velocity is determined by dividing your displacement (a vector pointing from your initial position to your end position) by the whole time.
The following formula can be used to determine the average net force, F b, necessary to reach a specific velocity, v:
F_b = (m * v) / t
Its net force, which is inversely related to its mass, is:
a = F_net / m
The final velocity can be related to the acceleration and time using the following kinematic equation because the fist's velocity is attained from rest:
v = a * t
When we enter the acceleration expression from Newton's second law into this equation, we obtain:

Identify the direction of net force. A car is driving across a flat roas ,assume no air resistance
Answers
Assuming the car is driving across a flat road with no air resistance, the direction of net force acting on the car will depend on the direction of the car's motion and the forces acting on it.
If the car is traveling at a constant velocity, then the net force acting on it is zero. This is because the forces acting on the car - such as the force of the engine, friction from the tires, and air resistance - are balanced and cancel each other out. However, if the car is accelerating or decelerating, then there is a net force acting on it. For example, if the car is accelerating forward, then the net force acting on it is in the forward direction. This is because the force of the engine pushing the car forward is greater than the opposing forces, such as air resistance and friction. Similarly, if the car is decelerating, then the net force acting on it is in the opposite direction of its motion. This is because the opposing forces are greater than the force of the engine, causing the car to slow down.

how much more light can a telescope with an 8-inch mirror gather compared to a telescope with a 2-inch mirror?
Answers
360 units more light can a telescope with an 8-inch mirror gather compared to a telescope with a 2-inch mirror.
The magnification power of a telescope means how much magnification telescopes can provide without making the image distorted. There is a rule known as the ‘60 rule’ or general rule of thumb which determines the magnification power.
For this, we need to multiply the diameter or the size of the mirror by 60. So if we have an 8-inch telescope, then we can say that this 8-inch is the diameter of that telescope.
So we can find that, 8×60=480, which is the upper limit of the 8-inch telescope.
2×60=120, which is the upper limit of the 2-inch telescope
The difference will be 480-120=360
