Answer:
Explanation:
The formula for the magnitude of a vector is
and then round to the hundredths place:
3.11 m. Since we are in Q2, we can also find the direction of this vector:
but since we are in Q2, we add 180 degrees to the result, getting the angle to be 115.3
Answer:
The average speed of the tourist is 88.89 km/h
Explanation:
Given;
distance of travel, d = 320 km
time of travel, t = 3.6 h
Average speed is given as;
average speed = distance / time
average speed = 320 km / 3.6 h
average speed = 88.89 km/ h
Therefore, the average speed of the tourist is 88.89 km/h
Answer:
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.

Brainliest???
Answer:
9.8 m/s/s, for earth 1.7 N on the Moon.
Explanation:
may i be marked brainliest?
The situation narrated above is a geometric sequence with first term equal to 10 and the common ratio equal to 0.87. Since there is no telling as to how low will the bounce be, the sequence is infinite.
The equation for the sum of the terms in an infinite geometric sequence with common ratio that is lesser than 1 is,
S = Ao/(1 - r)
Substituting,
S = (10 ft) / (1 - 0.87)
S = 76.923
We multiply the sum by two.
2S = 76.923 x 2 = 153.846
We subtract 10 from this because the first bounce does not travel twice.
<em>ANSWER: 143.846 ft</em>
