What do we know about the relative strength of the electric field around each object?
Vsevolod [243]

Answer:

A charged object in an electric field experiences a force due to the field. The electric field strength, E, at a point in the field is defined as the force per unit charge on a positive test charge placed at that point.

Objects 1 and 2 attract each other with a gravitational force of 12 units. If the mass of Object 2 is tripled, then the new grav
olasank [31]

Explanation:

Fgravity = G*(mass1*mass2)/D².

G is the gravitational constant, which has the same value throughout our universe.

D is the distance between the objects.

so, if you triple one of the masses, what does that do to our equation ?

Fgravitynew = G*(3*mass1*mass2)/D²

due to the commutative property of multiplication

Fgravitynew = 3* G*(mass1*mass2)/D² = 3* Fgravity

so, the right answer is 3×12 = 36 units.

A sample of ancient granite crust is dated using potassium-40. Scientists find that 50% of the potassium-40 has decayed to form
damaskus [11]
The find the approximate age of the granite one must know the half-life of potassium-40. The half-life of an element is the period of time in which half atoms of the same substance changes into the isotope of the element. The isotope of potassium-40 is Argon 40. Potassium-40 has a half-life of approximately 1.3 billion years. The rock is approximately 1.3 billion years old.

A kangaroo kicks downward with a 1000N force. According to Newton's Law the kangaroo is propelled into the air by:
bogdanovich [222]
<h3>Answer: B) his muscles</h3>

Explanation:

Specifically his leg muscles. As the leg muscles expand, they push down on the ground. Newton's 3rd law says that for any action, there's an opposite and equal reaction. That means a downward push into the ground will have the ground push back, more or less, and that's why the kangaroo will jump. The ground (and the earth entirely) being much more massive compared to the animal means that the ground doesn't move while the kangaroo does move. Perhaps on a very microscopic tiny level the ground/earth does move but it's so small that we practically consider it 0.

This experiment can be done with a wall as well. Go up to a wall and lean against it with your hands. Then do a pushup to move further away from the wall, but you don't necessarily need to lose contact with the wall's surface. As you push against the wall, the wall pushes back, and that causes you to move backward. If the wall was something flimsy like cardboard, then you could easily push the wall over and you wouldn't move back very much. It all depends how much mass is in the object you're pushing on.
