if an object is moving with constant speed then its distance time graph will be a straight line. a) along time axis b) along distance axis c) parallel to time axis d)inclined to time axis.

I’m not sure but the time and distance will be increasing while they required the distance time so my answer is ((A))

Explanation:

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000
