Answer: with a greater surface area, there will be a greater force of friction
Explanation:
Answer: Explanation:
If the net force on an object is doubled, its acceleration will double If the mass of an object is doubled, the acceleration will be halved .
Answer:
8684.2 kg/m³
Explanation:
Tension in the rope as a result of the weight = 8.86 N
Tension in the rope when submerge in water = 7.84
upthrust = 8.86 - 7.84 =1.02 N = mass of water displaced × acceleration due to gravity
Mass of water displaced = 1.02 / 9.81 = 0.104 kg
density of water = mass of water / volume of water
make volume subject of the formula
volume of water displaced = mass / density ( 1000) = 0.104 / 1000 = 0.000104 m³
volume of the object = volume of water displaced
density of the object = mass of the object / volume of the object = (8.86 / 9.81) / 0.000104 = 0.9032 / 0.000104 = 8684.2 kg/m³

Actually Welcome to the concept of distance formula.
Distance formula ==>

so applying this we get as,
D = underoot (9)^2 + (-5)^2
==> D = 10.29 units
distance = 10.29 units
Answer:
21 hours
Explanation:
well 30 x 20 = 600 than 21 = 630
