Answer:
30mph
Explanation:
7.5 miles / .25 hours = 30 mph
Answer:
Explanation:
a) Total distance traveled by the whale = 6.9 km + 1.8 km + 3.7 km = 12.4 km
b) the magnitude and the direction of the displacement of the whale = 6.9 km due east - 1.8 km due west = 5.1 due east
it final displacement = 5.1 km due east + 3.7 k due east = 8.8 km due east
c) average speed in km / hr = total distance traveled / total time = 12.4 km / 0.5 hr ( 30 min/ 60 min × 1 hr) = 24.8 km / hr
d) average velocity in km / h = total displacement / total time = 8.8 km / 0.5 h = 17.6 km/h
Answer:
its B because we're not talking about mass even tho most people would have chosen A cuz it says mass and u they would think its apart of density but if ur testing to see density ur figuring out which object will sink and which one will float so da reason why da penny snuck it cuz da density is greater den da water and copper has a better chance of sinking den floating so dats why its B I hope dis helps :3
Answer: To convert this into dimes it's basically like 25 divided by 10.
25 / 10 = 2.5, So you'd need two dimes and a nickel.
Let v1 be the initial velocity of 4m/s
Let v2 be the final velocity
v2=v1+(3s*2m/s^2) = 4m/s + 6m/s = 10m/s
