Phantasy [73]4 years ago

Answer:

Flying in a plane gives the notion of one exiting the earths atmosphere and also, there is the risk of exposure to dangerous cosmic radiation.

Nuclear power plants possesses great forms of chemicals and toxic elements that could lead to chemical radiation and further more, cause mutation of human cells which invariably brings cancer. There is the extreme health hazard to be weary of when in a nuclear power plant.

Being struck by lightning can be hazardous to ones health and could bring forth a number of health problems like; hearing and/or vision loss, irregular heartbeat,  headache, chest pain, hypersomnia, confusion,  shortness of breath, weakness, stiffness, and/or temporary paralysis.

Exposure to BPA in plastics has been connected to be cause of a number of fertility problems, male impotence, heart disease, and other conditions.

What do all of these problems have in common? They all are things you never see coming, you can't literally control the particles from nuclear plants, the forces handling the elevation and descending of planes, the chemical and physical nature of compounds involved in lightning production as compared to not exercising and knowing what could come from that. The side effects of not exercising can not be compared to the latter explained and those are life threatening processes.

1. What is the momentum of a 1550 kg car that is traveling leftward at a velocity of 15 m/s?
Alik [6]

Answer:

Momentum, p = 23250 kg m/s

Explanation:

Given that

Mass of a car, m = 1550 kg

Speed pf car, v = 15 m/s

We need to find the momentum of the car. The formula for the momentum of an object is given by :

p = mv

Substituting all the values in the above formula

p = 1550 kg × 15 m/s

p = 23250 kg m/s

So, the momentum of the car is 23250 kg m/s.

Equipotential surfaces a) make an angle of 45 degrees with the electric field. b) are parallel to the electric field. c) are per
Schach [20]

Answer:

Option c) are perpendicular to the electric field

Explanation:

Equipotential surfaces are perpendicular to the electric field. the electric field lines are projected outwards from the equipotential surface, i.e., the lines of the electric field are at 90^{\circ} to the equipotential surface.

Equipotential surface are those surfaces that have the same potential at any point on the surface. Thus the potential difference at any point on the surface is zero due to same potential.

Any charge particle on this surface will move in a perpendicular direction to the Coulombian force. No work is done by the force on a particle moving on an equipotential surface.

 How many centimeters are there in meter? b. 10 c. d 1000 e. 10000 100 2. A centimeter is equal to 1 inch b.½inch C 1/2.54 inch
astra-53 [7]

Answer:

a) There are 100 centimeters in 1 meter.

b) \texttt{A cm is equal to }\frac{1}{2.54}\texttt{ inch}

Explanation:

a) We have the conversion

         1 m = 100 cm

   So there are 100 centimeters in 1 meter.

b) 1 inch = 2.54 cm

    1cm=\frac{1}{2.54}inch

   \texttt{A cm is equal to }\frac{1}{2.54}\texttt{ inch}

6. When adding vectors graphically, the direction and length of each vector must:
Tanzania [10]

Answer:

Not be changed

Option: D

<u>Explanation:</u>

The physical quantity which has both ‘magnitude and direction’ is called vector. These vectors are represented by a line and an arrow, <em>the line represent the magnitude and arrow represent the direction of the physical quantity</em>. The vectors are added and subtracted according to the direction of the vectors.

According to the vector law addition while adding vectors direction and length of the vector is not be changed.<em> If the length of the vector changed the magnitude is also changed while so, while adding vectors length must not be changed. </em>

How does friction make it possible for you to walk across the floor?
Tema [17]

if we are walking on a perfectly smooth ground which has no friction our force would simply cancel out the force reverted by the ground and we would fall.

We need it to help push out feet off the ground

Hope those helps :)
