anzhelika [568]3 years ago
5 0

Explanation:

A) Use Hooke's law to find the spring constant.

F = kx

40 N = k (0.4 m)

k = 100 N/m

B) Period of a spring-mass system is:

T = 2π √(m / k)

T = 2π √(2.6 kg / 100 N/m)

T = 1 s

Frequency is the inverse of period.

f = 1 / T

f = 1 Hz

What is the force of gravity (from the Earth) on the 700kg satellite if it’s 10km above the Earths surface?
joja [24]

Answer:

The force of gravity on a 700 kg satellite if its 10 km above Earth's surface is given by

    = {\frac{(6.674\times 10^{-11}N. m^2/kg^2)(5.97\times 10^{24}kg) }{(10\times10^3)^2} = 3984378 m / s^{2}

Explanation:

The force of gravity on a 700 kg satellite if its 10 km above Earth's surface is given by

    = {\frac{(6.674\times 10^{-11}N. m^2/kg^2)(5.97\times 10^{24}kg) }{(10\times10^3)^2} = 3984378 m / s^{2}

If X be a vector 3 X represents  3 added to X  3 times of X  the ratio of X and 3  None
jolli1 [7]

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.
