Answer:
Explanation: F=umg where u is coefficient of kinetic friction.
But F=ma.
a = u^2/2S
U= 425km/hr = (425*1000)/3600 =118m/s
S= 6.7km = 6700m
a = 118*118/ (2*6700) = 1.04m/s
u = 1.04/9.8 =0.11
You find out what they are for example water,oxygen etc. you know wat i mean
Answer:
1. For a hot summer day, 35 degrees Celsius is most appropriate.
2. For room temperature, 20 degrees Celsius is most appropriate.
3. Aluminum's density is found by dividing mass by volume. 45 / 15 = 3 g/mL. The density is 3 g/mL.
4. Volume is found by multiplying length x width x height. 2cm x 5cm x 4cm equals 40 cm. We then divide the mass by volume to find density. 80 / 40 = 2 g/cm³. The density is 2 g/cm³.
