the relative enrichment in what isotope in venus' atmosphere is evidence of a significant loss of water over time?

Answer:

The final velocity of the car can be calculated using the equation:

v = u + at

where:

v = final velocity

u = initial velocity (since the car starts from a full stop, the initial velocity is 0)

a = acceleration (0.12 m/s^2)

t = time (unknown, but can be calculated using the distance and velocity)

To find the time, we can use the distance and velocity formula:

d = ut + (1/2)at^2

75 = 0 + (1/2)(0.12)(t^2)

t = sqrt(75/(1/2)(0.12))

t = sqrt(625/0.06)

t = sqrt(10416.67)

t = 102.41 seconds

Now we can substitute the values for u, a and t into the first equation to find the final velocity:

v = u + at

v = 0 + (0.12)(102.41)

v = 12.29 m/s

The magnitude of the final velocity of the car is 12.29 m/s.

The second block weighs one kilogram.

A mass measurement reveals how much matter is there in an object.

Usually, the metric systems of grams, kilograms, and tonnes are used to compute it.

As we know that F = ma.

Considering that the force applied to the first block and the second block are equal.

The acceleration of the first block is 0.2 m/s^2 and the acceleration of the second block is 0.1 m/s^2, we can set up the following equation:

F = ma

where F is the force exerted on both blocks, m1 is the mass of the first block (0.5 kg), a1 is the acceleration of the first block (0.2 m/s^2), m2 is the mass of the second block, and a2 is the acceleration of the second block (0.1 m/s^2).

So substituting,

F = m1 * a1 = m2 * a2

Rearranging for m2

m2 = F / a2

m2 = (F / 0.1 m/s^2)

m2 = (F/0.1) = m1 * (a1/a2)

m2 = (0.5kg * (0.2/0.1)) = 1kg

So, the mass of the second block is 1 kg.

(a) We can find the kinetic energy of the sprinter by:

KE = 1/2 * 65.0 kg * (10.0 m/s)^2 = 3250 J

Then, we can use this same equation to find the speed of the elephant, but with its mass (3000 kg):

KE = 1/2 * 3000 kg * v^2 = 3250 J

Solving for v, we get: v = sqrt(3250 J / (1/2 * 3000 kg))

And the speed of the elephant would be around 4.19 m/s.

(b) In order for a larger animal to move, it requires more energy than a smaller animal because larger animals have more mass, and as a result, more energy is needed to accelerate and maintain their motion. This increased energy demand is met by an increase in the animal's metabolic rate.

In strength, elephants are the strongest mammals and the strongest land animals. African elephants can weigh up to 6,350kg and they can carry up to 9,000kg, the weight of 130 adult humans.

The graph of y=3e^(-t/4) is shown below: Position (y) on the vertical axis and time (t) on the horizontal axis.

The horizontal axis is a reference line on a graph that runs horizontally (left to right) and is used to plot data points. It is also known as the x-axis, and it typically represents the independent variables of a graph. The horizontal axis is used to visually display quantitative values, such as time, distance, or cost. When graphing a mathematical equation, the horizontal axis typically shows the real numbers that are being used in the equation.

The graph starts at y=3 when t=0 and then decreases in a curved line as time increases. This is because the exponent term is negative, so the entire function is decreasing as time increases. Specifically, the graph follows the shape of the exponential decay function e^(-t/4). As time increases, the value of y decreases exponentially, approaching 0 as t approaches infinity.

The acceleration of block m1 is (ma-ma-mulo/im.mpma).

Acceleration is the rate at which an object's velocity with respect to time changes. It is a vector quantity to accelerate (in that they have magnitude and direction). The direction of the net force acting on an object determines the direction of its acceleration.

The acceleration of block m1 (ma) can be determined by analyzing the net force acting on it, which is equal to the tension in the string connected to it, minus the weight of the block.

Tension in the string connected to m1 is equal to the tension in the string connected to m3, since the two strings are light and inelastic. Therefore, the net force acting on m1 is equal to T - m1g, where T is the tension in the string and g is the acceleration due to gravity.

The tension in the string is equal to the acceleration of m3, since

T = m3a. Therefore, the net force acting on m1 is equal to m3a - m1g.

m1 is connected to m2 and m3, so the acceleration of m1 is dependent on the masses of m1, m2 and m3.

Therefore, the acceleration of block m1 is (m3-m1-m2)/(m1+m2+m3) which corresponds to option D) (ma-ma-mulo/im.mpma).

The velocity at which the bucket spins is 4.91m/s and the range of speeds is  between 4.91 m/s and 17.3 m/s.

a) The diagram is attached

b) FN - mg = m(v²/r)

c) v = 4.91 m/s

d) (4.91 < v < 17. 3 ) m/s

a. The free-body diagram for the glass when it is at the top of the circle would show the glass being acted upon by several forces. At the top of the circle, the glass is subjected to its weight (mg) acting downward, the normal force (FN) exerted by the bucket on the glass, and the tension (T) in the string.

b. The net force on the glass at the top of the circle can be represented by the following equation:

FN - mg = m * a

FN - mg = m(v²/r)

where FN is the normal force, m is the mass of the glass, g is the acceleration due to gravity, and a is the acceleration of the glass.

c. To prevent the glass from falling out, the normal force between the glass and the bucket has to be greater than zero, meaning the tension force should be greater than the weight of the glass. So we can use the net force equation.

T = m (v² / r) + mg

T = (0.5 kg)(v² / 1.5 m) + (0.5 kg)(9.8 m/s^2)

T > 0

Solving for v we get:

v > √( 9.8*1.5 ) = 4.91 m/s

d. The tension on the string is given by the equation T = m(v²/r)

Therefore, tension on the string is greater than 100 N when v > √(100*1.5/0.5) = √(300) = 17.3 m/s

Therefore the range of speeds she can keep the glass in the bucket and prevent the string from breaking is between 4.91 m/s and 17.3 m/s.

Distance is the amount of space between two objects or points. It is typically measured in units such as meters, feet, or miles. Distance can also be measured in a more abstract sense, such as the amount of time it takes for something to happen or the amount of effort required to complete a task.

Distance can also refer to the difference between two things, such as the difference between two people’s opinions on a particular topic. Distance can also refer to physical separation, such as the distance between two people who are in different countries or cities. Distance can also be used to express the size of something, such as how far a car can travel on a single tank of gas.

The force on the firefly is greater than the force on the bus.

The concept of action-reaction pair is described by Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In this scenario, the force of the firefly striking the bus is the action and the force of the bus striking the firefly is the reaction.

However, the force on the firefly is greater than the force on the bus. This is because the firefly is much smaller and less massive than the bus, so the force required to stop the firefly is much greater than the force required to stop the bus. Additionally, the firefly's impact on the bus would be negligible, while the bus' impact on the firefly would be fatal.

To solve this problem, we need to use the concept of centripetal force, which is the force that keeps an object moving in a circular path. The centripetal force is given by the equation:

F = m * a

where F is the centripetal force, m is the mass of the object and a is the centripetal acceleration.

The centripetal acceleration is given by the equation:

a = v^2 / r

where v is the velocity of the object and r is the radius of the circular path.

The radius of the circular path in this case is the length of the string (12cm). The angle of 35° is not needed for solving the problem.

Now we can substitute the value of a into the equation for the centripetal force:
