Answer:
Civil engineers design major transportation projects. Civil engineers conceive, design, build, supervise, operate, construct and maintain infrastructure projects and systems in the public and private sector, including roads, buildings, airports, tunnels, dams, bridges, and systems for water supply and sewage treatment.
if the vector sum of the force applied by you and the force applied by another person is zero, then the object will not accelerate since the net force on the object is zero in this case. hence the object will not move at all or if it was already moving , will move at constant velocity.
if the vector sum of the force applied by you and the force applied by another person is non-zero, then the object will not accelerate since there is net force on the object in this case. hence the object will accelerate.
2. Unselected The stated situation isn’t possible.
3. Unselected It has the same net charge as 11 protons.
4. Unselected It has the same net charge as 11 electrons.
Answer:
3. It has the same net charge as 11 protons.
Explanation:
An electrically neutral object contains the same number of protons and electrons. Therefore, if 11 electrons are removed from it, there will be 11 more protons compared to the number of electrons in the object. Thus, the object It has the same net charge as 11 protons.
Energy radiated from the surface of a protostar which is inreturn is replaced by energy released through gravitational contraction.
This keeps a protostar in thermal equilibrium

Explanation:
A specie with no charge and containing one or more number of unpaired electrons is known as a free radical.
These free radicals tend to attain stable configuration by gaining an electron from another atom. Hence, they fill their outer energy levels.
For example, a free radical of chlorine will readily combine with a hydrogen atom in order to attain stability and it leads to the formation of a new chemical bond between the hydrogen and chlorine atom.
As a result, it will form a hydrogen free radical.
Thus, we can conclude that free radical is a highly reactive chemical species with one or more unpaired electrons.
A free radical is a highly reactive chemical species with one or more unpaired electrons. They actively participate in chemical reactions due to their need to complete their electron shell. These radicals can be both harmful and beneficial, depending on their context.
A free radical is a highly reactive chemical species with one or more unpaired electrons. These species are reactive because they seek to complete their electron shell by forming pairs, making them eager to engage in chemical reactions.
For instance, in combustion processes, free radicals like hydroxyl (OH) play a crucial role. Despite their reputation for causing damage in biological systems, free radicals are also beneficial as they are used by the immune system to neutralize pathogens.

a triple beam balance
a mass meter
all of the above
Answer;
-A triple beam balance
Explanation;
-Mass is the amount of matter in an object. Move to a different planet and an object's weight will change, but its mass will be the same. There are a couple of ways to measure mass. The Mass of an object doesn't change when an object's location changes. Weight, on the other hand does change with location.
-Mass is measured by using a balance comparing a known amount of matter to an unknown amount of matter. Weight is measured on a scale.
Mass is measured using scales, a triple beam balance, or a mass meter.
Scales are commonly used for everyday measurements, where an object's weight is indirectly measured by the force it exerts on a spring or load cell.
A triple beam balance is a type of mechanical balance that uses a combination of sliding weights to determine mass.

Answer: The kinetic energy of the ball at the maximum height is zero.
Explanation -
As per the question, the ball is moving vertically upwards. Every time it's velocity will decrease and it becomes zero at the maximum height.
Whole of ball's initial kinetic energy is converted into potential energy at maximum height.
Thus we can conclude that the kinetic energy is zero at the maximum height.
