Answer:C (198 seconds)
Explanation: The cyclist makes the first lap in (180.00 - 6.00) = 174.00 seconds. The average time per lap for all three circuits is (600.00 - 6.00) = 594/3 = 198 seconds.
Answer:
44.7 N
Explanation:
The gravitational force between the objects is given by:

where
G is the gravitational constant
m and M are the masses of the two objects
r is the distance between the centres of the two objects
In this problem, we have:
is the mass of the sphere
is the Earth's mass
is the Earth's radius, while h=310 km is the altitude of the sphere, so the distance of the sphere from Earth's centre is

Substituting into the equation, we find

Answer:
Q=mc(T2-T1)
Explanation:
Ti is the temperature
m is mass
c is specific heat capacity for steam
Q is heat, [Q]=J
Answer:
Facilitated diffusion.
Explanation:
Facilitated diffusion is the movement of molecules across a biological cell membrane by the use of a membrane protein.
It is a spontaneous passive movement and it can also be reffered to as FACILITATED TRANSPORT or PASSIVE-MEDIATED TRANSPORT.
