An average person can reach a maximum height of about 60 cm when jumping straight up from a crouched position. during the jump itself, the person's body from the knees up typically rises a distance of around 50 cm. to keep the calculations simple and yet get a reasonable result, assume that the entire body rises this much during the jump.

Answers

Final answer:

The question is related to Physics and deals with kinematic equations. With the supplied information, one can calculate elements such as velocity or applied force in the jump.

Explanation:

The subject of the question pertains to the field of Physics, specifically the area of kinematic equations which deal with the motion of objects. The provided information in the question pertains to the rise of a person's body during a jump. Given the average height of 60cm that a person typically attains and the approximate rise of the body from the knees up being 50cm, these figures can be used in a Physics context to determine different factors of the jump such as velocity or force applied.

For example, using the equation of motion (height = 0.5 * gravity * time^2) where gravity is around 9.8 m/s^2, you can calculate the time taken to reach maximum height. We can calculate this using the initial velocity combined with the gravity force. Furthermore, the force applied can be calculated knowing the mass of the person and the acceleration (which is the initial velocity divided by the time).

A scientist told his student assistants that he had sorted groups of mice by their intelligence and asked the assistants to assess the groups’ maze-solving abilities. The scientist had not actually sorted the mice by intelligence. The students rated the “highest intelligence” group of mice as the best maze solvers and the “lowest intelligence” group as the worst maze solvers. What was the scientist trying to demonstrate by doing this experiment?Experimental subjects should never be put into groups.
Mice should not be judged by their intelligence.
Higher intelligence mice are better maze solvers.
People can introduce their own biases into an experiment.

Answers

The right answer for the question that is being asked and shown above is that: "People can introduce their own biases into an experiment." the scientist trying to demonstrate by doing this experiment is that People can introduce their own biases into an experiment.

Which event can be excluded from a list of interactions among Earth's spheres?A solar flares
B volcanic eruption
C fracking for natural gas
D hurricane

Answers

Final answer:

Solar flares can be excluded from a list of interactions among Earth's spheres because they are not directly related to interactions among the geosphere, hydrosphere, atmosphere, and biosphere.

Explanation:

The event that can be excluded from a list of interactions among Earth's spheres is A solar flares. Solar flares are not directly related to interactions among Earth's spheres, which include the geosphere, hydrosphere, atmosphere, and biosphere.

On the other hand, volcanic eruptions, fracking for natural gas, and hurricanes are all examples of interactions among Earth's spheres. Volcanic eruptions involve the release of gases and materials from the geosphere into the atmosphere. Fracking for natural gas involves extracting resources from the geosphere and potentially impacting the hydrosphere. Hurricanes involve interactions between the atmosphere and the hydrosphere, resulting in powerful storms.

Therefore, the correct answer is A solar flares.

A ball of clay sinks when placed in water. The same piece of clay floats if it is made into the shape of a boat.Why does the clay float when made into the shape of a boat?
a. The clay is less dense when stretched into the shape of a boat.
b. The buoyant force is greater on the clay when it has a spherical shape.
c. The boat shape displaces a greater volume of water than the ball shape.
d. The weight of the clay boat is less than the weight of the clay ball.

Answers

The correct answer is definitely d. The weight of the clay boat is less than the weight of the clay ball.
In such situations, the point that we should take as a basis to resolve a question is weight. If the weight of clay is less than that of a clay ball, the clay will float.

Answer:

c. The boat shape displaces a greater volume of water than the ball shape.

How does the density of the metal in the crushed can compare with the metals density before the can was Crushed

Answers

dens = mass/volume. after crushing, vol less so density more. the actual density of the metal is the same, density of can changes

Final answer:

The density of a metal can, whether it is crushed or not, remains the same because density is an intrinsic property of matter, dependent only on the mass and volume of the substance. Changing the can's shape alters its volume but does not affect its mass or its density.

Explanation:

The density of a substance is the ratio of its mass to its volume (Density = Mass / Volume). This physical property is intrinsic to the substance, meaning it doesn't change regardless of the quantity or form the material is in.

When you crush a metal can, you're changing its shape and thereby altering its volume. However, the mass remains the same because you haven't removed or added any material. As a result, the density of the metal in the crushed can stays the same as the metal's density before the can was crushed.

Let's consider a practical example: a block of brass and a piece of rebar. Both have the same mass and are made of the same metal, but the block of brass has a larger volume. Nevertheless, the densities of these substances remain constant. That's because density is an intrinsic property, reflecting the compactness of material in a substance. Hence, even though you change the can's shape (thus, its volume), you have no impact on the metal's density.
