a 25.05kg mass being pushed by a 10 N force should be 15.05
24kg pushed by 8N should be 16
<span>To solve for m in the equation F = ma, you must divide both side of the equation by a. This will make the equation look like F/a = ma/a. Since m is being multiplied by a, dividing it will cancel out. Now making the final equation look like F/a=m and/or m=F/a.</span>
Answer:
D. They have the same number of valence electrons
Explanation:
- The periodic table arranges elements into rows known as periods and columns known as groups or families.
- Elements in the same group share similar chemical properties.
- Additionally, they have the same number of valence electrons. For example, elements in group I have one valence electrons while those in group II have two valence electrons.
- Elements in the same period share similar features such as having the same number of energy levels. For example elements in period 4 have four energy levels.
Answer:
3. x 10⁸m/s
Explanation:
Given parameters:
Frequency of wave = 7.8 x 10⁶Hz
Unknown:
Speed of the wave = ?
Solution:
All electromagnetic radiation has a speed of 3. x 10⁸m/s in free space.
No matter the frequency and wavelength, they all have the same speed which is the same as the speed of light.
