What makes it possible for light from the sun to cause changes to genetic material?
Answers
Answer:
But some light from the sun, like ultraviolet (UV) rays, are not good for us, or specifically, the DNA in our cells. UV rays can cause mutations, or errors, in that genetic material. When mutations are introduced into our genetic code, it can cause serious health problems, like skin cancer

4-wheeler
Explanation:
I was thinking that you could say this:
My design is that the 4-wheeler will detect, with the help of technology, when something is approaching or you are very close to it. As the object gets closer, it will beep faster and louder. When the 4-wheeler beeps really fast and really loud, it means that you are about to crash or you are in danger. It will stop and launch an airbag so you stay safe. When the 4-wheeler stops, it will make a signal to let people know that you have stopped.
I am so sorry if this wasn't the response that you were looking for.

Occurs when the particles in one part of an object vibrate more and collide with neighboring particles, making them transfer energy.
Different materials conduct heat at different rates. Metals are generally good conductors of heat compared to non-metals (paper, wood, and plastics).
Solids are better conductors than liquids because the particles in solids are tightly packed together.
What is thermal energy?Thermal energy is the energy associated with the random motion of particles in a substance. It is a form of kinetic energy created from the vibrational and rotational motion of atoms and molecules in a substance.
All objects contain thermal energy and when two objects of different temperatures are in contact, heat flows from the hotter object to the colder object until they reach a state of thermal equilibrium. Thermal energy is used in many applications such as heating, cooling, and even cooking food.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
kinetic energy is given as
5) when speed is 6 m/s
kinetic energy is given as

How does an increase in altitude affect the climate?
Answers
Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.

Analyze the forces acting on the crate shown in the diagram. Explain why the crate will not move in the direction of the applied force. (Fapp.)
Answers
The crate will not move in the direction of the applied force because in the image there are two forces.
What is force ?A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Force is used to describe a body's tendency to modify or change its state as a result of an external cause. When force is applied, the body can also alter its size, shape, and direction.
Contact forces and act at a distance forces are the two different types of forces. Your daily use of force is evident. Basically, push and pull are forces. You exert force on an object when you push against it or pull against it.
Thus, The crate will not move in the direction of the applied force because in the image there are two forces.

Through testing and observation, scientists have recorded the following characteristics of Maxoids. Maxoids reproduce via sexual reproduction. One parent carries the Maxoid eggs for 12 weeks before they hatch. After hatching, juvenile Maxoids continue to grow for seven months. To acquire energy for growth, Maxoids consume a peculiar liquid substance native to the planet Moby. The Maxoids' cells use this energy, as well as large amounts of water, to carry out important functions. The Maxoids are sensitive to changes in internal temperature. Sometimes they dig holes and lay in them to cool down if they get too warm.

Chemical Weathering Rocks are changed by chemical and physical weathering. During chemical weathering, the composition of the rock is changed. Extreme heat and pressure within Earth can also cause rocks to change chemically. Physical weathering is the breaking down of rock by wind, water, ice, temperature change, and plants. It changes the shape and size of rocks, but it does not change their properties.

Rocks expand and contract when they are heated and cooled which cause them to break. Physical weathering is experienced to the crust of earth. The last state of physical weathering is sand. Rocks that have some cracks are undergoing frost wedging.
What is weathering?Weathering is a geographical process of deterioration of rocks and minerals into parts and eventually into dust and sand. Thermal stress, a phenomenon caused by temperature variations, can also contribute to mechanical weathering.
The expansion and contraction of rock is influenced by temperature changes. The rock's structure deteriorates as this occurs repeatedly. Physical weathering and mechanical weathering disintegrates rocks without any chemical changes and it happens to the earth's crust.
Erosion of rocks eventually results in formation of sand. Frost wedging is a process by which ice erodes the rocks having cracks. It is also called ice wedging.
