8. The moon has about 1/6th the gravity of the Earth. How would the potential energy of an object be different on the moon if it

topjm [15]

The potential energy on the moon would be 1/6 of the potential energy on Earth

Explanation:

The potential energy of an object is the energy possessed by the object due to its position in a gravitational field, and it is given by

$PE=mgh$

where

m is the mass of the object

g is the strength of the gravitational field

h is the height of the object above the ground

In this problem, the potential energy of the object on the Earth is

$PE=mgh$

On the Moon, the gravity is

$g'=\frac{1}{6}g$

Therefore, if the same object (same mass) is placed at the same height $h$ on the Moon, its potential energy would be

$PE' = m(\frac{1}{6}g)h = \frac{1}{6}(mgh) = \frac{1}{6}PE'$

A cave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. The lift i

bija089 [108]

Answer

Mass m = 78 kg

Vertical height in each stage h = 11 m

(a).

Initial speed u = 0

Final speed v = 1.1 m / s

$v^2=u^2 + 2 as$

$1.1^2 = 2 a \times 11$

a = 0.055 m/s²

Work done

$W_a= m g h + \dfrac{1}{2}mv^2$

$W_a= 78\times 9.8 \times 11 + \dfrac{1}{2} 78 \times 1.1^2$

$W_a = 8408.4 + 47.19$

$W_a = 8455.59 J$

(b).Work done

$W_b= mgh$

W_b = 78× 9.8× 11

$W_b= 8408.4 J$

c)

Work done

$W= m g h + \dfrac{1}{2}m(v_f-v_i)^2$

Where V = final speed

= 0

v = 1.1 m / s

for deceleration a = -0.055 m/s²

now,

$F_L = 56 (-0.055+9.8) = 545.72 N$

W_c = 545.75 × 11

$W_c = 6003.25 J$

How could glacial marks on one continent be similar to glacial marks on another continent far away?

BigorU [14]

Answer:

Plate Tectonics

Explanation:

Plate tectonics is the scientific theory that the continents move around due to due plate tectonics and the movement of magma under the crust. This explains why some fossils of the same kind are found on other continents, and same goes for the Glacial Marks.
