The amount of material must also fall to [1%] of its initial amount for the activity of the supplied radioactive isotope to decrease to [1%] of its initial level. As a result, it will take the radioactive isotope [6.645T] years to decay to around [1%] of its original value.

As a result, 50% of the original parent nuclei are still present after one half-life, 25% after two half-lives, etc. The half-life and the initial quantity of radioactive atoms present both affect how much radiation is produced by a radioactive source.

So after 3 half lives, or 6 days, around 12.5% of the total radioactive material will still be present.

Answer:

is constant

Explanation:

When an object is moving with uniform circular motion, the object’s tangential speed is constant.

The force of sliding is the force required to keep an object moving at a constant velocity while it is sliding on a surface.

This force is equal in magnitude to the force of friction acting between the object and the surface, but opposite in direction. The force of friction acts between two surfaces that are in contact and is directed opposite to the direction of motion. When an object is sliding on a surface, the force of friction acts to slow the object down and eventually bring it to a stop.

If the object is moving at a constant velocity, the force of friction is equal in magnitude to the force applied to the object, but opposite in direction. This force is known as the force of sliding.

A body's velocity is the rate at which its displacement alters with respect to time. A vector quantity with both magnitude and direction is velocity. The meter/second unit of measurement for velocity.

Given that Skyler whose mass is 74.5 kg is moving across at 9.52 m/s while holding a 2.05 kg carefully packed snowball.

forward speed of the snowball = 15.9 m/s.

Let the Skyler velocity after throwing the snowball = v.

According to principle of conservation of momentum;

Total initial momentum = total final momentum

⇒ (74.5 + 2.05)9.52 = 74.5×v + 15.9×2.05

Now we have that;

weight = mass * acceleration due to gravity

mass = weight/ acceleration due to gravity

mass = 12,000 N / 10 m/s^2

The time interval during which the speed of the wheel is increasing is 4 s.

The temporal rate at which angular velocity changes is known as angular acceleration. The standard unit of measurement is radians per square second.

The angular velocity at time t = 0, is ω₁ = - 6.00 rad/s.

The angular velocity at time t = 10.0 s, is ω₂ = +4.00 rad/s.

= ( 4.00 - (-6.00))/10 rad/s²

= 1.0 rad/s²

Hence, angular velocity becomes zero at time = ( 0 - ( -6))/1.0 s = 6 s.

So, during t = 0 to t = 6s, the clockwise angular velocity of the wheel decreases from 6.00 rad/s to 0.00 rad/s and  during t = 6s to t = 10s , the counterclockwise angular  velocity of the wheel increases from 0.00 rad/s to +4.00 rad/s.

The greater efficiency achieved with the curved blades of a Pelton wheel is due to the fact that the curved shape of the blades allows them to more effectively capture and use the energy of the water jet.

In a Pelton wheel, water is jetted through a nozzle onto the blades of a turbine, which rotates and converts the energy of the water jet into mechanical work. The shape of the blades plays a significant role in the efficiency of the turbine. Curved blades are more efficient than straight blades because they can capture and use more of the kinetic energy of the water jet.

The curved shape of the blades creates a more efficient flow of water over the surface of the blade, which allows the blade to extract more energy from the water jet. This results in a higher torque and power output from the turbine, leading to a more efficient conversion of water energy into mechanical work.

The planet with an orbital eccentricity most like the orbital eccentricity of the Moon is Earth. The orbital eccentricity of a celestial body is a measure of how much its orbit deviates from a perfect circle. An orbital eccentricity of 0 represents a perfect circle, while an orbital eccentricity of 1 represents a parabolic orbit.

The orbital eccentricity of the Moon is approximately 0.0549, which is relatively small compared to other celestial bodies. The orbital eccentricity of Earth is also small, with a value of approximately 0.0167. This means that both the Moon and Earth have orbits that are relatively close to being circular.

In contrast, many other planets in the solar system have much larger orbital eccentricities. For example, Mars has an orbital eccentricity of 0.0935, while Mercury has an orbital eccentricity of 0.2056.
