Answer:
D) Heavier objects need a greater force to accelerate according to F=ma.
Explanation:
The force of gravity acting on an object is equal to:
F = mg
where m is the mass of the object and g is the acceleration due to gravity. According to the formula, heavier objects (objects with greater mass, m) have a larger force of gravity acting on them.
However, the acceleration of an object towards the ground is given by:

therefore, we see that if the object is heavier (larger mass, m), the force of gravity (F) must also be larger in order to have the same acceleration a.

Aaaaw noooo. :(
Explanation:
what did they say to u and what state do u live in. I will help u stand up to them. I have taken down many bullies before by using words. in fourth grade, my friend was getting bullied by the class, then yelled and stood up for her. they all fell silent and never bullied her, or any of my friends again. For whatever reason they bully u is probably d.u.m.b. which means they r really d.u.m.b. Also, U should try finding out a lot of personal info about them that they dont want anyone to know. also tell the principal. Is ur mom nice, or mean? if shes nice, she'll support u and fight for u, which means u should address
Answer:
the magnitude of the dog's total displacement to the nearest tenths = 53.12°
Explanation:
Given that:
a dog walks 8.0m due to the north and 6.0 m due east.
We can determine the magnitude of the dog's total displacement by using the Pythagoras theorem.
Consider the north direction be the opposite and the east direction to be the adjacent, therefore the hypotenuse will be the dog's total displacement.
So, suppose hypotenuse is represented by a
the opposite represented by b, and the adjacent represented by c
Then;
a² = b² + c²
a² = 8² + 6²
a² = 64 + 46
a² = 100
a =
a = 10.0 m
However, the magnitude of the dog's total displacement is calculated by taking the tangent of the system.
tan θ = opposite / adjacent
tan θ = b/c
tan θ = 8/6
tan θ = 4/3
tan θ = 1.333
θ = tan⁻¹ (1.333)
θ = 53.12
the magnitude of the dog's total displacement to the nearest tenths = 53.12°
I believe the correct answer from the choices listed above is option B. The salt bridge in the diagram would be a paste. I would like to assume that the paste consists of the Na2SO4 salt. <span>The </span>purpose<span> of a </span>salt bridge<span> is not to move electrons from the electrolyte, rather to maintain charge balance because the electrons are moving from one half </span>cell<span> to the other.</span>
Answer:
Explanation:
Let mass of the apple be m . Force on it at surface of the planet can be expressed as follows
F_R = G Mm / R²
Where M is mass of the planet.
Let at at height h the gravitational force on apple be 0.3 F_R
0.3 F_R = G Mm / ( R +h)²
Dividing the two equation
1 / 0.3 = ( R +h)²/ R²
( R +h)/ R = 1.825
h = .825 R
b )
If we go deep inside the planet to get force on apple equal to .3 F_R
.3 F_R = G 4/3 π ( R - h )³ d m / (R-h)² [ d is density of planet ]
.3 F_R = G 4/3 π ( R - h ) d m
F_R = G Mm / R²
F_R = G 4/3πR³d m / R²
F_R = G 4/3πR d m
dividing two equations
0.3 = ( R - h ) / R
h = .7 R
