Answer:

B. A dish of water is placed in the freezer and turns solid

Explanation:

it is a physical change because it can return to its original state by physical means. the other options are chemical changes because things like color change, bubbles or fizzing, and odor change all indicate a chemical change and cannot return to the original state it was in before.

How do scientists construct models of atoms and molecules?
9966 [12]
Mr. Roentgen's x-rays allowed scientists to measure the size of the atom. The x-rays were small enough to discern the atomic clouds. This was done by scattering x-rays from atoms and measuring their size just as Rutherford had done earlier by hitting atoms with other nuclei starting with alpha particles.

BMX bicycle rider takes off from a ramp at a point 1.2 m above the ground. The ramp is angled at 40∘ from the horizontal, and th
podryga [215]

Answer:

The ramp lands at an horizontal distance of 3.989 m

Explanation:

Range: Range is defined as the horizontal distance of a projectile from the point of projection to the point where the projectile hits the projection plane again. It is measure in meters (m)

R = U²sin2∅/g..................................... Equation 1

Where R = The horizontal distance from the end of the ramp, U = rider's speed, ∅ = the ramp's angle to the horizontal.

<em>Given: U = 6.3 m/s, ∅ = 40°, g = 9.8 m/s²</em>

<em>Substituting these values into equation 1</em>

<em>R = [6.3²sin2(40)]/9.8</em>

<em>R = (39.69×sin80)/9.8</em>

<em>R = 39.69×0.985/9.8</em>

R = 3.989 m

Thus the ramp lands at an horizontal distance of 3.989 m

Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound. It is represented by
quester [9]

A study assessing the effect of anxiety Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound.

Everyone experiences anxiety occasionally, but persistent anxiety can reduce your quality of life. Though likely best known for altering behavior, worry can have negative effects on our physical spherical. Anxiety speeds up our heartbeat and breathing, concentrating blood flow to the parts of our brains that need it. You are spherical ready for a challenging situation by having this extremely bodily reaction. Test performance may be impacted by anxiety. According to studies, spherical with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have indicated that female students have greater levels of test anxiety than male students.
