(i) • there is force applied to an objects
• the object moves
• the object moves in the same direction as the direction of the force
(ii) workdone = force x distance
= 23 x 34
= 782Joules
Examples of student-led organizations are:
- Academic and educational organizations
- Community service organization
- Media and publications organizations
- Political or multicultural organizations
- Recreation and sports organizations
- Student government organizations
- Religious and Spiritual organizations
The benefits of getting involved in any of these are many. They include but are not limited to:
- It helps one to learn more about oneself
- It is a great place to develop leadership skills
- It offers the opportunity for people to build life-long networks
- Skills learned in class can be practiced and honed in these organizations
- Soft skills such as team-intellignce, and social intelligence can be learned in these organizations
- Valuable experiences that count in real-life jobs can be learned here
- It is also an opportunity to give back to the community and to have fun

If its atomic number is 48, then it has 48 protons in the nucleus
of each atom. Any more mass than that is supplied by the neutrons
that are mixed in there with the protons.
If the mass is 167, and 48 of those are protons, then there are
(167 - 48) = 119 neutrons
in each nucleus.
Answer:
Elements in a period have wide range of chemical properties.
Explanation:
- Period is the row of chemical elements's arrangement in the periodic table. It is numbered from 1 to 7.
- In period as we move towards right the atomic number of element constantly increases along with the change in chemical properties.
- As we move from left towards right in period, the valence electron number regularly increases in every element.
- This valence electron differs the reactivity of the elements.
Answer:
No.
Explanation:
Given that Kevin decides to soup up his car by replacing the car's wheels with ones that have 1.4 times the diameter of the original wheels. Note that the speedometer in a car is calibrated based on the tire's diameter and on the distance the tire covers in each revolution. (a) Will the reading of the speedometer change ?
Considering the formula
V = wr
Where
V = linear speed
W = angular speed
r = radius of the wheel.
But W = 2πrf
Where the the 2 and pi are constant. The radius of the first wheel will be small but counter balance with the larger frequency.
While the radius of the second wheel may be large but it will be of a small frequency.
We can therefore conclude that the reading on the speedometer will not change. Because speedometer will read the linear speed V.
