Answer:

\Large \boxed{\mathrm{Mercury, \ Uranus, \ Earth, \ Neptune}}

Explanation:

Earth ⇒ 9.8 m/s²

Mercury ⇒ 3.7 m/s²

Neptune ⇒ 11.2 m/s²

Uranus ⇒ 8.9 m/s²

W=m \times g

\sf {Weight=mass \times acceleration \ due \ to \ gravity}

The weight of a person can differ on different planets, but the mass stays the same. The greater the acceleration due to gravity, the greater the weight.

Arranging the planets in increasing order based on a person’s weight on the planet:

Mercury, Uranus, Earth, Neptune

Answer:

Mercury, Uranus, Earth, Neptune

Explanation:

Weight is mass times gravity.  The greater the gravity, the greater the weight.

Find the electric field at a point midway between two charges of +40.0 × 10−9 c and +60.0 × 10−9 c separated by a distance of 30
Anna [14]
The point midway between the two charges is located 15.0 cm from one charge and 15.0 from the other charge. The electric field generated by each of the charges is
E=k_e  \frac{q}{r^2}
where
ke is the Coulomb's constant
Q is the value of the charge
r is the distance of the point at which we calculate the field from the charge (so, in this problem, r=15.0 cm=0.15 m).

Let's calculate the electric field generated by the first charge:
E_1 = (8.99 \cdot 10^9 Nm^2 C^{-2} ) \frac{+40.0 \cdot 10^{-9} C}{(0.15 m)^2}=1.6 \cdot 10^4 N/C

While the electric field generated by the second charge is
E_2 = (8.99 \cdot 10^9 N m^2 C^{-2} ) \frac{+60.0 \cdot 10^{-9} C}{(0.15 m)^2}=2.4 \cdot 10^4 N/C

Both charges are positive, this means that both electric fields are directed toward the charge. Therefore, at the point midway between the two charges the two electric fields have opposite direction, so the total electric field at that point is given by the difference between the two fields:
E=E_2 - E_1 = 2.4 \cdot 10^4 N/C - 1.6 \cdot 10^4 N/C = 8000 N/C

An airplane is accelerating forward due to a force of 3320 newtons acting
Darya [45]

Two opposite forces generate a force whose magnitude is the difference of the two magnitudes, and whose direction is the same of the strongest one.

We have 3320 newtons forward, and 550 backwards.

So, the net force is forward, and has magnitude 3320-550=2770

A small charged sphere is attached to a thread and placed in an electric field. The other end of the thread is anchored so that
VMariaS [17]

Answer:

E = 9.66\times 10^{-6} N/C

direction is Horizontal

Explanation:

As we know that the string is horizontal here

so the tension force in the string is due to electrostatic force on it

now we will have

F = qE

so here the force is tension force on it

F = 6.57 \times 10^{-2} N

Q = 6.80 \times 10^3 C

now we have

6.57 \times 10^{-2} = (6.80 \times 10^3)E

E = 9.66\times 10^{-6} N/C

direction is Horizontal

andreev551 [17]

Answer:

Chemical substances in food that have specific functions in your body are called Nutrients. Examples: proteins, fats, carbohydrates, vitamins, and minerals

Explanation:

These chemical substances keep our body healthy.

These chemical substances prevent the premature aging.

They help our body to fight against diseases.

They build the new tissues and cells for growth.

And in short, they help in the growth, development of our body.
