According to Newton's second Law of motion, if the mass of an object is 10 kg and the force is 10 newtons, then the acceleration is 1m/s².
<h3>How to calculate acceleration?</h3>
The acceleration of a moving body can be calculated by dividing the force of the body by its mass.
According to this question, the mass of an object is 10 kg and the force is 10 newtons, then the acceleration can be calculated as follows:
acceleration = 10N ÷ 10kg
acceleration = 1m/s²
Therefore, according to Newton's second Law of motion, if the mass of an object is 10 kg and the force is 10 newtons, then the acceleration is 1m/s².

#SPJ1
Answer:
Both student are correct.
Explanation:
Given :
Student 1: Nuclear fusion powers the Sun, so activity like sunspots and flares must be caused by a change in the fusion rate or the type of fusion.
Student 2: Fusion is constant, keeping the Sun a nice temperature; changes on the surface are caused by the Sun's magnetic field
There are two types of nuclear reaction,
Fusion:
Two lighter atom combine together are produce new atom.
In case of fusion large amount of energy produces and fusion powers the sun. In case of sun two hydrogen atom combine together and helium produces so statement 1 is true.
Sun posses large magnetic field due to magnetic field sun spot created like magnet there are two poles N and S, magnetic field lines goes from N to S.
Sun spot are produces because of change in magnetic field and change in temperature. So statement 2 is also true.

Answer:
D. 2.7 N
Explanation:
Applying
F = kq'q/r²................ Equation 1
Where F = force, k = coulomb's constant, q' = first charge, q = second charge, r = distance between the charge
From the question,
Given: q' = +3.0×10⁻⁷ C, q = +4.0×10⁻⁷C, r = 2.0×10⁻² m
Constant: k = 8.98×10⁹ Nm²/C²
Substitute these values into equation 1
F = ( +3.0×10⁻⁷)(+4.0×10⁻⁷)(8.98×10⁹)/(2.0×10⁻²)²
F = 26.94×10⁻¹ N
F = 2.694 N
F ≈ 2.7 N
