Find the x coordinate xcm of the center of mass of the system. Express your answer in terms of m1 , m2 , x1 , and x2

Answers

Answer 1

The position of center of mass will be x = (x₁m₁ + x₂m₂) / m₁ + m₂

The center of gravity of a body or system of particles is defined as the point at which the entire mass of the body or all the masses of the system of particles appeared to be concentrated.

In physics, we can say that the center of mass is the point at the center of the distribution of mass in space (also known as the equilibrium point) where the weighted relative position of the distributed mass sums to zero.

Simply put, the center of gravity is the position that is relative to the object. We can say that it is the average position of all parts of the system or it is the mean location of the mass distribution in space. It is the point where a force is usually applied that results in linear acceleration without any angular acceleration.Mathematically, COM is  (x₁m₁ + x₂m₂) / m₁ + m₂

where, x₁ and x₂ are the positions of the objects and m₁ + m₂ are the masses of the objects respectively.

what is the source of heat for most hot springs and geysers, and how is this reflected in the distribution of these features?

Answers

Geothermal heat is the source of heat for most hot springs and geysers.

Geothermal heat, or heat that originates from deep within the Earth, heats hot springs. Water may come into touch with extremely hot rock heated by magma in volcanic zones. Hot springs in volcanically active areas may create superheated water that is so hot than immersion can be dangerous or fatal. The temperature of rocks within the Earth also rises with depth in non-volcanic regions; this temperature rise is known as the geothermal gradient. Water can generate hot springs if it percolates far enough through the crust, coming into contact with hot rocks along the way.

The most well-known geothermal feature is a geyser. Due to intricate interior plumbing, each geyser has distinct characteristics. In a location of volcanic activity, geysers often demand that vast volumes of groundwater fill subsurface cavities. These deep caverns' water is warmed by neighbouring magma. Suddenly, a portion of the water turns to steam and rapidly expands. An burst of heated air and steam forces the suspended in the water column violently out of the vent. Repeating this cycle is possible frequently. Yellowstone National Park contains Old Faithful, a geyser that has been erupting once in every 65 minutes for centuries.

A kid rides a scooter down the sidewalk with an constant speed of 3.0 m/s for 7.0 seconds, then uniformly increases speed to 9.0 m/s in 5.0 seconds. What is the kid's total displacement? (How far along the sidewalk did the kid travel?)

Answers

The kid's total displacement is 66m.

What is distance?

The formula for calculating distance, d = st, or "distance equals speed times time," can be used. Because they both refer to the amount of movement per unit of time, such as miles per hour or kilometers per hour, speed and rate are comparable. The equation r = s = d/t holds if speed s = rate r.

In first case

Distance = speed × time

Distance = 3×7

Distance = 21m

In second case

Distance = speed × time

Distance = 9×5

Answers

The speed of the ball that is launched into a parabolic path after it hits the balloon is 7.07 m/s.

Given that,

Initial speed of the ball = 10 m/s

Angle at which the ball is launched = 45°

The path of the ball which hits the balloon at the top of its flight follows a  parabolic trajectory

Taking off an airplane, braking a car, cornering a go-kart at high speed are all sensations of acceleration.

Acceleration is the name we give to any process that changes velocity. Velocity is speed and direction, so there are only two ways to accelerate. Either change speed, change direction, or change both.

No matter how fast you run, you can't accelerate unless you change speed and direction. So a jet traveling along a straight line at a constant speed of 800 miles per hour will not accelerate even though it is traveling very fast because its speed does not change. When the jet lands and comes to a sudden stop, it accelerates while decelerating.

Answers

3.12 mg of sample will remain after 39.9 hours if the half life of iodine is 13.3 hours.

What does half-life mean?

Half life of the process is the time necessary for the reaction rate to fall to one-half its original amount. A statistic that is connected to the reaction's rate constant is the split of a first-order order reaction.

Briefing:

Given, Half life of iodine is 13.3 hours. so,

Half life t1/2 = ln 2/ K

               k = 0.693 / t1/2

                  = 0.693 /13.3 hours

The flow time is based on rate law which would be different for each emotions. A first-order interaction is one in which only one reactant's concentration affects the rate of the reaction. As a result, it is sometimes referred to as a unimolecular reaction. For this kind of reaction, the rate equation is: The first order reaction's rate constant is,

Answers

The fraction of the neutrons kinetic energy transferred to the atomic nucleus is 0.296.The final kinetic energy of the neutron is 3.034 × 10⁻¹³ JWhat is conservation of momentum?

Conservation of momentum states that the momentum remains constant within the problem region. Momentum is neither created nor destroyed, it is changed only by the action of force in the sense of Newton's laws of motion.

For head on elastic collision both momentum and energy are conserved.

Initial Momentum = Final Momentum

v = mv₁ + 12.5mv₂

m = mass of neutron

v = final velocity of neutron after collision

v₁ = initial velocity of neutron

v₂ = velocity of atom

v = v₁ + 12.5v₂

Energy before = energy after

½ m v² = ½ m v₁² + ½ (12.5m) v₂²

v² = v₁² + 12.5 v₂²

We want to find the fraction of the neutron's kinetic energy is transferred to the atomic nucleus.

KE/KE = (½ (12.5m) v₂²) / (½ m v²)

KE/KE = 12.5 v₂² / v²

KE/KE = 12.5 (v₂ / v)²

We need to find the ratio v₂ / v.

Solve for v₁ in the momentum equation and substitute into the energy equation.

v₁ = v − 12.5 v₂

v² = (v − 12.5 v₂)² + 12.5 v₂²

v² = v² − 25 v v₂ + 156.25 v₂² + 12.5 v₂²

0 = -25 v v₂ + 168.75 v₂²

0 = -25 v + 168.75 v₂

25 v = 168.75 v₂

v₂ / v = 25 / 168.75

v₂ / v = 0.148

Hence, the fraction of the kinetic energy transferred is:

KE/KE = 14.1 (0.148)²

KE/KE = 0.296

Part 2/2

If a fraction of 0.296 of the initial kinetic energy is transferred to the atomic nucleus, the remaining 0.704 fraction must be in the neutron.

Therefore, the final kinetic energy is:

KE = 0.704 (4.31 ×10⁻¹³ J)

A ship travels across the water at a speed of 30 mph while angled 30 degrees south of east. The water is travelling 20 degrees east of north at a speed of 5 miles per hour. Vector for the ship is 25.98i - 15j mi/h.

What is the direction of the water current?

The water is also travelling at a speed of 5 miles per hour at an angle of 20° south of east, which suggests that it is moving in the first quadrant at an angle of 90° - 20° = 70° east of north.

The period of a simple pendulum is T = 2π√l/g and T = 2π√m/k

What is the period of a simple pendulum?

The time period of a simple pendulum is equal to the time it takes to complete one Oscillation. The period of a simple pendulum depends on the length of the string, and acceleration due to gravity. In simple pendulum , the mass of the pendulum does not after the period.

But in spiral spring, the period depend on the elastic constant 'k' and mass of the load.

Therefore the period of a simple pendulum is can be given in two forms:

T = 2π√l/g and

T = 2π√m/k

where m is the mass of the load

l is the length of the spring and g is the acceleration due to gravity.
