Answer:

the sheets approach while the object is near

Explanation:

An electroscope is an apparatus that has two metal sheets attached, when these sheets have a charge and distribute evenly between them and the sheets repel.

When I approach an object charged with a counter (negative) charge, part of the charge of the electroscope moves near the charged external object, to neutralize the electric field, so as the charge on one of the plates decreases the electroscope has approached , as the objects are not touched the system remains in this configuration while the object is close. When the object is released, the electric field it creates disappears, so the positive charges repel inside the electroscope and the sheets repel to the initial position.

In short, the sheets approach while the object is near

Answer:

See the answers below

Explanation:

In this problem, we must be clear about the concept of weight. Weight is defined as the product of mass by gravitational acceleration.

We must be clear that the mass is always preserved, that is, the mass of 15 [kg] will always be the same regardless of the planet where they are.

$W=m*g$

where:

W = weight [N] (units of Newtons)

m = mass = 15 [kg]

g = gravity acceleration [m/s²]

Since we have 9 places with different gravitational acceleration, then we calculate the weight in each of these nine places.

Mercury

$w_{mercury} = 15*3.8\\w_{mercury}= 57 [N]\\$

Venus

$w_{venus}=15*8.8\\w_{venus}= 132 [N]$

Moon

$w_{moon}=15*1.6\\w_{moon}=24[N]$

Mars

$w_{mars}=15*3.7\\w_{mars}=55.5 [N]$

Jupiter

$w_{jupiter}=15*23.1\\w_{jupiter}= 346.5[N]$

Saturn

$w_{saturn}=15*9\\w_{saturn}=135[N]$

Uranus

$w_{uranus}=15*8.7\\w_{uranus}=130.5[N]$

Neptune

$w_{neptune}=15*11\\w_{neptune}=165[N]$

Pluto

$w_{pluto}=15*0.6\\w_{pluto}=9[N]$

Mass have no effect for the projectile motion and u want to know the height "h"
first,
find the vertical and horizontal components of velocity
vertical component of velocity = 12 sin 61
horizontal component of velocity = 12 cos 61
now for the vertical motion ;
S = ut + (1/2) at^2
where
s = h
u = initial vertical component of velocity
t = 0.473 s
a = gravitational deceleration (-g) = -9.8 m/s^2

h=[12×sin 610×0.473]+[−9.8×(0.473)2]

u can simplify this and u will get the answer

h=.5Gt2

H=1.09m
