Answer:
1. Dry Beans - 591.75 kg/m^3
2. Flour - 593 kg/m^3
3. Wax - 900 kg/m^3
4. Wet sand - 2039 kg/m^3
5. Chalk - 2499 kg/m^3
6. Talcum Powder - 2776 kg/m^3
7. Copper - 8960 kg/m^3
Explanation:
Make sure your units are the same
Answer:
u = 11.6 m/s
Explanation:
The end of a launch ramp is directed 63° above the horizontal. A skier attains a height of 10.9 m above the end of the ramp.
Maximum height, H = 10.9
Let v is the launch speed of the skier. The maximum height attained by the projectile is given by :
u = 11.6 m/s
So, the launch speed of the skier is 11.6 m/s. Hence, this is the required solution.
Answer:
The formula for speed is speed=<u>d</u><u>i</u><u>s</u><u>t</u><u>a</u><u>n</u><u>c</u><u>e</u>
time
Explanation:
to work out what the units are for speed,you need to know the units for distance and time.In this example,distance is in metres(m) and time is in seconds (s) , so the units for speed is metre per second (m/s).
Answer:
1 kg lead to earth is greater attraction as mass of earth is much more than 1kg lead.
Explanation:
Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass
Hey there,
<span>They interfere essentially like any other form of wave.

Hope this helps :))
