Question: which statement provides a complete scientific discription of an object in motion?
Answer: the marble moved 30 cm north in 6 seconds.
Explanation: motion is a change in position of an object over time an object's motion cannot change unless it is acted upon by a force

C standards are based on observable, reproducible natural phenomena.
Answer: 3.7×10¹²watts
Explanation:
Radiation is one of the mode of heat transfer and modes differs from each other based on their medium of heat transfer. Radiation is a process of transferring heat energy from one point to another without heating the intervening medium (no material medium is required).
According to Stefan's law of radiation, the rate of emission of radiant energy is directly proportional to the fourth power of its absolute temperature.
Mathematically, R = eAT⁴
e is constant of proportionality called emissivity. Emissivity varies depending on the type of body being considered.
For the question, we are considering black body and emissivity of black body is 1 being a perfect body.
A is the area of the body
T is the absolute temperature
e = 1
A = 0.5cm²
T = 1650°C
Rate of radiation = 1×0.5×1650⁴
= 3.7×10¹²watts.
The hole will therefore radiate 3.7×10¹²watts
Answer:
Explanation:
F = qvB
Where F equal to the magnetic force on the particle.
q = charge on the particle
v = velocity of the particle
B =Magnetic field
F = 0.520N
q = 7.4 μC = 7.4×10-⁶C
v = 3×10⁵m/s
B= ?
B = F/qv
B = 0.520/(7.4×10-⁶ ×3×10⁵)
B = 0.234T.
