Answer: position (x) and time (t)
Explanation:
A body is said to be in motion when its position changes with time with respect to a stationary observer.
Following are the types of motion:
<u>Uniform motion</u>: When equal amount of distance is covered in equal intervals of time.
<u>Non-Uniform motion</u>: When unequal amount of distance is covered in equal intervals of time.
Motion can be of the following types as well:
<u>Rectilinear motion</u>: when object moves in a straight line.
<u>Circular motion</u>: when object moves in a curved path.
<u>Periodic motion</u>: when motion repeats itself in fixed intervals of time.
Thus, in order to define motion, only two variables are required: position and time. Measuring these variables can determine whether the object is in motion or not and the type of motion.
Answer:B
Explanation:A is wrong, because there are multiple suns, not just one
C is wrong, because the universe is not known as the milky way, just our solar system. D is wrong, because the universe isnt gradually getting smaller, its gradually getting bigger, and yeah, the universe is mainly empty space, So B
Answer:
Maximum speed, v = 36 m/s
Explanation:
Given that,
The radius of the curved road, r = 120 m
Road is at an angle of 48 degrees. We need to find the maximum speed of stay on the curve in the absence of friction. On a banked curve, the angle at which it is cant is given by :
g is the acceleration due to gravity
v = 36.13 m/s
or
v = 36 m/s
So, the maximum speed to stay on the curve in the absence of friction is 36 m/s. Hence, this is the required solution.
Answer:
Water temperatures are slow to heat up, It takes 4 times the energy to heat up water than to heat air. Water also "feels" colder because water is a more efficent medium than air to cool our body down.
