A. False. If it is high tide in one place on Earth, the place exactly opposite to it will also have a high tide.

The gravitational attraction of the Moon and the inertia of the oceans cause two tidal bulges on opposite sides of the Earth.

B. True. Cassini used flybys of Venus, Earth and Jupiter as slingshots to reach Saturn.

C. True. The whole solar system moves around the galaxy.

D. True. If a planet’s gravity is not strong enough, the molecules in its atmosphere will have enough kinetic energy to escape into space.

E. False. The mass of an object is constant, but its weight changes according to the gravity of the planet.

F. False. To find the mass of an object, divide its weight by gravity.

$F = mg$ or weight = mass × gravity

∴ Mass = weight/gravity

Select ALL correct answers. The contact force is caused by: A. Atoms randomly crashing into each other B. The charged particles

Inessa [10]

Answer:

A. Atoms randomly crashing into each other

E. The force of one object pushing against the force of another object.

Explanation:

Forces can be classified into two categories based upon the the mode of transfer or application:

1. Contact forces

2. Non-contact forces

Contact forces are the ones which require the physical contact of the matter to get transferred and tend to create the affect. Whereas non-contact forces have the field property which transfers the affect of force from one point to another without any physical contact of the matter or the medium.

Atoms crashing onto each other have some mass and velocity which upon collision impacts the other atoms exerts a contact force.
The interaction between the charged particles due to their charges is always due to the electric field be it electron or proton, be it within an atom or out of an atom.
The force between any two objects pushing or pulling each other is also possible only due to contact.

Write the complete balanced equation for the following reaction:

Assoli18 [71]

Explanation:

An equation that consists of same number of atoms on both reactant and product side is known as a balanced chemical equation.

For example, $C_{7}H_{6}O + O_{2} \rightarrow CO_{2} + H_{2}O$

Number of atoms on reactant side are as follows.

C = 7

H = 6

O = 3

Number of atoms on product side are as follows.

C = 1

H = 2

O = 3

Therefore, to balance this chemical equation we multiply $O_{2}$ by 8 on reactant side. Whereas we multiply $CO_{2}$ by 7 and $H_{2}O$ by 3 on product side.

Therefore, the balanced chemical equation will be as follows.

$C_{7}H_{6}O + 8O_{2} \rightarrow 7CO_{2} + 3H_{2}O$
