Answer:
6 J
Explanation:
Gravitational Potential Energy can be calculated using the formula:
PE = mgh
where m is mass of object in <em>k</em><em>g</em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>g is the gravitational acceleration of 10 m/s^2
h is the height at which object is thrown in <em>m</em><em>.</em>
Hence, by substituting in the values, we get:
GPE = (4.0)(10)(0.15)
<u>6</u><u> </u><u>J</u>
Hence, the potential energy is <u>6</u><u> </u><u>J</u><u>.</u>
C is your answer im pretty sure

Answer:
u= 755 m/s
Explanation:
Lets take
Velocity of bullet = u m/s
The velocity of system after collision ,v= 5 m/s
m= 10 g = 0.01 kg
M= 1.5 kg
From linear momentum conservation( because there is no any external force on the system)
Pi= Pf
m u = ( m +m) v
0.01 x u= (1.5 + 0.01) x 5
u= 755 m/s
<span>They would feel that the water is cold.
</span> The atmosphere is heated both by the Sun and by the Earth's surface. Water radiates heat differently than land, so the air temperature over the ocean is usually different than the air temperature over land. <span>
The difference in air temperature over land compared to over water causes convection currents in the atmosphere. How would a person at the beach experience these convection currents?
</span>They would feel that the water is cold.
NOT:
They would feel the heat of the Sun.
They would feel that the sand is hot.
<span>They would feel wind as the air moves.</span>
