Answer:

change the

time
distance
force.

Explanation:

P = W/time

W = F*d

You have control over how fast you go up the stairs.

You also have control over how far up the stairs you go.

Therefore the answer is

time
distance

If you don't like distance as an answer, you can carry something up the stairs -- anything that increases F will do.

In a control system, an accelerometer consists of a 4.63-g object sliding on a calibrated horizontal rail. A low-mass spring att

Masteriza [31]

Answer:

8.4 N/m

Explanation:

m = Mass of block = 4.63 gm

g = Acceleration due to gravity = $9.81\ \text{m/s}^2$

x = Displacement of spring = 0.45 cm

a = Acceleration of subject = 0.832g

k = Spring constant

Force is given by

$F=ma$

From Hooke's law

$F=kx$

$ma=kx\\\Rightarrow k=\dfrac{ma}{x}\\\Rightarrow k=\dfrac{4.63\times 10^{-3}\times 0.832\times 9.81}{0.45\times 10^{-2}}\\\Rightarrow k=8.4\ \text{N/m}$

The force constant of the spring is 8.4 N/m.

A proton moves at constant velocity in the +y direction, through a region in which there is an electric field and a magnetic fie

Ivenika [448]

Answer:

a) F_{e} - F_{m} = 0, b) v = 666.67 m / s

Explanation:

For the proton to move y-axis the sum of the electric and magnetic force must be zero, therefore

$F_{e} - F_{m}$ = 0

a) ∑ F = 0

F_{e} - F_{m} = 0

b) we write the forces

q E = q v B

v = E / B

Let's calculate

v = 300 / 0.45

v = 666.67 m / s

How far away is the furthest artificial satellite orbiting earth?

rusak2 [61]

Real-time distance and velocity data is provided by NASA and JPL. At a distance of 153.88 AU (23.020 billion km; 14.304 billion mi) from Earth as of September 5, 2021, it is the most distant artificial object from Earth. The probe made successful flybys of Jupiter, Saturn, and Saturn's largest moon, Titan.
