Answer:

784N

Explanation:

Yo need to multiply the mass of the person by th Earth's gravity, which we know is 9.8m/s²

80kg*9.8m/s² = 784N

Answer:

The weight of the person on the Earth's surface is 784N

Solution:

The weight and mass are separate things. The weight of the person includes the gravitational acceleration along with the mass of the person as per Newton’s second law.

So, $Weight = Mass\times GravitationalAcceleration$

Here the mass = 80 kg

We know the gravitational acceleration = $9.8 m/sec^2$

So the weight of the person = $Mass \times Gravitational acceleration = (80\times9.8)N = 784N$

A ramp with a mechanical advantage of 8 lifts objects to a height of 1.5 meters how long is the ramp

AlekseyPX

Given data:

M.A. = 8 (No units),

Ramp height (h)= 1.5 m, lifted,

Determine how long is the ramp=?

General formula 

 Mechanical Advantage = (Ramp length) ÷ (Ramp height),

 M.A = l ÷ h 

 8 × 1.5 = l = 12 m long

length of the ramp l ramp = 12 m

In 1909, galileo first looked at the milky way using very powerful binoculars

anastassius [24]

Galileo first studied the Milky Way through his telescope in January, 1610 not 1909. Until his observations, the Milky Way was thought to be a band of wispy whitish clouds passing through the heavens. To Galileo's amazement, instead of seeing just a nebula (the Greek work for cloud) the milky wisps resolved into innumerable tiny stars, so crowded together that, without the aid of a telescope, the light from those stars simply blended together.
