The answer is B
If we assign speed variable x; and time variable y; then;
xy=150
(y-1) (x+5) = 150
xy + 5y - x – 5 = 150
(remember xy = 150), therefore;
5y – x = 5
X = 25
Y = 6

The correct answer to the question is : Photosphere i.e it is the region whose temperature is 6000 degree celsius.
EXPLANATION:
The Sun has many regions starting from photosphere to central core. Different regions of the sun has different temperature.
The temperature of the sun is due to the fusion occurring inside it. The core temperature is immense due to the gravitational attraction which produces more heat there. Gradually the temperature decreases as we move away from the sun core.
As per the question, the temperature is given as 6000 degree celsius.
The region of the sun which corresponds to this temperature is photosphere. The temperature of photosphere varies from 5500 degree celsius to 7500 degree celsius. The temperature of sunspots found in the sun may be lower than the average temperature of the photosphere.
Hence, the correct answer is Photosphere.
a graduated cylinder
an eye dropper
a beaker
a buret
Answer: a buret
A graduated cylinder and a beaker cannot be used. This is because the basic solution needs to be added drop by drop. This is not possible using a graduated cylinder or a beaker because it is difficult to pour drop by drop from these. An eye dropper cannot be used because it does not measure the volume being added.
A buret would be the best choice because it precisely measures the amount being added and we can add the basic solution to the acid drop by drop.
Rock concerts and whispers are examples of a high-amplitude sound and a low-amplitude sound.
The largest displacement of sound wave constituents from their resting positions is referred to as amplitude. It stands for the loudness or intensity of a sound, to put it simply. Here are some illustrations of both high and low-amplitude sounds:
High Amplitude Sound: An illustration of a high amplitude sound is a rock concert with loudspeakers blaring songs at full intensity. The concert speakers produce sound waves with a tremendous amplitude, creating a powerful, strong sound that can be heard from a great distance.
Low Amplitude Sound: A low amplitude sound is something like the sound of a whisper. The sound created when someone whispers is calm and soft and not as loud as a rock concert, since the sound waves produced have a tiny amplitude.
In both cases, how loud or soft the sound is perceived by our ears depends on the amplitude of the sound waves. Low-amplitude sounds are soft and quiet, but high-amplitude sounds are strong and loud.
Hence, rock concerts and whispers are examples of a high-amplitude sound and a low-amplitude sound.
