Physics
1 answer:
jolli1 [7]2 years ago
3 0

Answer:

The correct option is;

3 times of X

Explanation:

The algebraic properties of a vector are;

Multiplicative identity for real numbers 1

1P = P for each P

Scalar associative property = r(sP) = (rs)P

Scalar distributive property (r + s)P = rP + sP

Vector distributive property r(P + Q) = rP + rQ

Additive inverse of a vector such that a vector P has an inverse -P such that we have;

P + (-P) = 0

Vector associative property (P + Q) + R = P + (Q + R)

Vector commutative property P + Q = Q + P.

What is the distance between a 2000 kg truck and a 3000 kg truck if the gravitational force between them is 0.00006 N?
Andrew [12]

Answer:

A. 2.58m

Explanation:

Using the formula;

F = GMm/r²

M and  m are the masses

G is the gravitational constant

r is the distance between the masses

Substitute

0.00006 = 6.67*10^-11(2000)(3000)/r²

0.00006r² = 6.67*10^-11*6000000

0.00006r² = 40.02*10^-5

0.00006r² = 0.0004

r² =  0.0004/0.00006

r² = 6.66

r = 2.58m

Hence the distance between them is 2.58m

17. Ms. Lopez is being chased by a Komodo dragon. She has an initial velocity of 7 m/s
exis [7]

Answer:

Cant say for sure, its been a while sense ive done this, but im almost certain its 70

Explanation:

Take the zero off of your 10 s

Then go 7 m/s x 1 s

Which equals 7

Add the zero back to the end of your answer

10 -- 0 = 1 x 7 = 7 ++ 0 = 70

(PS, two of the same sign is just adding a number to the end of your original answer, that is not what it actually stands for in mathematical terms but that is what i'm using to make it clearer as to whats happening)

I'm not too good at explaining and formulas but i hope this helped
