Answer:
A) 29.4 m 17.0 m; B) 2 m
Explanation:
If a vector is 34.0 m in length and is directed 60.0° east of north (which means 30.0° over the horizontal), then its coordinates will be:
Horizontal: (34.0 m)cos(30.0°)=29.4 m
Vertical: (34.0 m)sin(30.0°)=17 m
If one person walks 8.0 meters in a straight line and then walks 5.0 meters in another straight line, then the minimum displacement would be to go back over his tracks, displacing himself 8m-5m=3m, while the maximum displacement would be going straight ahead, displacing himself 8m+5m=13m. Any answer outside this interval is impossible (2m).
Answer:
92km
Explanation:
Given parameters:
Duration of the journey = 6hrs
Average speed = 58km/hr
Now, let us find the total distance of the journey;
Distance = Speed x time
Distance = 58 x 6 = 348km
So;
Average speed for the first 4hrs = 64km/hr
Time = 4hrs
Distance = 64 x 4 = 256km
For the rest of the journey, the student will cover;
= 348km - 256km
= 92km
B. velocity is the speed in any given direction.
Answer:
Given :
To find the product of 183.5 and 10², move the decimal point in 183.5 _____ places to the right because 10² has _____ zeros.
To Find :
We need to fill the spaces.
Solution :
We know, when number with positive power of 10 is multiplied with another number we need to shift the number to the right hand side by the number of zeroes.
So, To find the product of 183.5 and 10², move the decimal point in 183.5 to right places to the right because 10² has two zeros.
Hence, this is the required solution.

The air particle inside the balloon will collide more with each other and the temperature inside the balloon will increase.
As a person squeezed and applies the pressure to the outside of a balloon, the air particle inside the balloon gains energy and collide with each other, the particle of the air also try leave the balloon surface will implies equal pressure on the wall of the balloon, as the pressure outside the balloon increase, the inside pressure will also increase.
