You examine two weather maps of your area for two different days. One map shows isobars that are closely spaced; the other shows isobars that are far apart. Predict the difference in weather conditions for those days.

a) Isobars that are closely spaced indicate a large pressure difference over a
small area and light winds. Isobars that are far apart indicate a small pressure
difference over an area and strong winds.

b) Isobars that are far apart indicate a large pressure difference over a small
area. Isobars that are closely spaced indicate a small pressure difference over
an area.

c) Isobars that are far apart spaced indicate a large pressure difference. Isobars
that are closely spaced indicate a small pressure difference.

d) Isobars that are closely spaced indicate a large pressure difference over a
small area and strong winds. Isobars that are far apart indicate a small
pressure difference over an area and light winds.

The answer is: letter d, Isobars that are closely spaced indicate a large pressure difference over a small area and strong winds. Isobars that are far apart indicate a small pressure difference over an area and light winds.

Explanation:

An "isobar" is a line that is being drawn on a weather map. The areas with same pressures are being connected by the isobar. The value of the pressure is indicated by "millibars." This is vital when it comes to locating areas on the weather map that have high pressure and low pressure.

Once the isobars are closely spaced, it indicates that there is a large pressure difference over a small area. There is a strong pressure gradient because the speed of the wind is high. This is, thus, associated with stronger winds.

On the contrary, isobars that are far apart have weak pressure gradients. This means that the wind speed is light thus resulting to lighter winds.

Thus, this explains the answer.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction

There is a theory that indicates that dinosaurs became extinct when about 65 million years ago, a large asteroid hit the earth surface. dust caused by this collision blocked the sunlight reaching the earth's surface and many forms of life became extinct due to the cold. fearing this threat, how large the radius of an asteroid should you be looking for if the dangerous asteroid size is approximately the same as the one that killed the dinosaurs? available data suggests that about 18% of that asteroid's mass ended up as a dust spread evenly over earth after eventually settling out of the upper atmosphere. about 0.0180 g/cm^2 of dust, which is chemically different than the earth's rock, covered the earth's surface. typical asteroids have a density of about 1.9 g/cm^3. now that we know the size of the asteroid, how much energy was released during impact, assuming all of it was just the kinetic energy of the asteroid right before the impact?

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?
