Answer:
C. Protons have an electrical charge, but neutrons have no charge.
Explanation:
Protons and neutrons both are parts of nucleus and they stay inside the nucleus due to large nuclear force between them
Mass of proton and mass of neutron is almost same or in more precisely we can say that neutrons are slightly heavy than protons
mass of neutrons is 1.008 amu while mass of protons are 1.007 amu.
the main different between them is that protons are positively charged and their charge is same as that of charge of electron
while neutrons are electrically neutral and they do not have any charge on them.
so correct answer will be
C. Protons have an electrical charge, but neutrons have no charge.
Answer:
Newtons 3rd law
Explanation:
Newtons third law states; for every action, there is an equal but opposite reaction force.
The action force in this case in the foot kicking the soccer ball, but the reaction force is the ball 'kicking' back on the foot. This reaction force has the same magnitude as the action force, but opposite in direction, which is why the foot is left stinging.
Momentum = 0.5 * 4 = 2
to conclude the man’s velocity after he throws the piece of equipment, divide
this number by the man’s mass.
v = 2/90
This is about 0.0222 m/s. To know if he can move 6 meters at velocity in
4minutes, use the following equation.
d = v * t, t = 4 * 60 = 240 s
d = 2/90 * 240 = 5⅓ meters.
This is ⅔ of a meter from the spaceship. To know the velocity that he must have
to move 6 meter, use the same equation.
6 = v * 240
v = 6/240
This is about 0.00416 m/s.
His final momentum = 90 * 6/240 = 2.25
To know the velocity of the package, divide this number by the mass of the
package.
v = 2.25/0.5 = 4.5 m/s
Answer:
NASA satellites help scientists study Earth and space. Satellites looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy that Earth absorbs and emits. And satellites monitor wildfires, volcanoes and their smoke.

Hope this helps! :) have a great day.
Answer:at an angle North of east
Explanation:
Given
Velocity of Wind
Velocity of bee relative to wind
In vector Form
To get the final velocity in North cos component of will balance velocity of wind
Therefore Final velocity is 8.33sin(36.77)=4.98 m/s due to North
at an angle North of east
