Pete's speed can be calculated using the formula for speed which is distance divided by time. He covers a distance of 150 meters in 18 seconds, resulting in a speed of approximately 8.3 meters per second.
To calculate Pete's speed in meters per second, we can use the formula for speed which is given by distance/time. In this case, the distance that Pete covers is 150 meters, and the time he takes is 18 seconds. So, we divide 150 by 18 to get Pete's speed. When we perform this calculation, we obtain a speed of approximately 8.3 meters per second. Therefore, the correct option is (a) 8.3 m/s.
This equation allows us to calculate the speed for any given distance and time and is an essential component of physics and many real-world situations such as determining travel times, planning routes, and even in sporting events to measure performance.

Air from the equator moves toward the poles slower than the ground below it, so friction causes the air to veer east. In contrast, air from the poles moves toward the equator faster than the ground below it, so friction causes it to veer to the west.

A ray at which angle would produce the most glare is at 70 degrees. The answer is letter D. the greater the incident of light is, the greater is its index of refraction and thus having greater angle to produce a light ray.
The ray more the incidence ray, the more will be the reflected ray. As angle of incidence is to angle of reflection.
Glare can be defined as the difficulty in seeing the object due to more brightness. The bright light such as the direct sunlight or the reflected sunlight or the headlight at the nighttime.The more the intensity the more will be glare.
Hence, the ray that will produce most glare is 70 degree.
A rigid, 2.50 L bottle contains 0.458 mol He. The pressure of the gas inside the bottle is 1.83 atm. If 0.713 mol Ar is added to the bottle and the pressure increases to 2.05 atm, what is the change in temperature of the gas mixture?
