Answer:
They have no charge and are present in the nucleus of an atom. They have a negative charge and travel around the nucleus of an atom. They have a positive charge and travel around the nucleus of an atom
Explanation:
Answer:
ans: 4.34 × 10^(-9) N
Explanation:
mass of Mya say (m) = 65 kg
mass of spaceship say (M) = 1600 kg
universal gravitational constant(G) =6.67 × 10^(-11) Nm²/kg²
separation distance (d) = 4m
so,
gravitational force (F)= GMm/d²
=( 6.67 × 65 × 1600) / ( 10¹¹ × 4²)
= 4.34 × 10⁴ / 10¹³
= 4.34 × 10^(-9) N
For the answer to the question above,
Ricardo goes a distance (magnitude) of 27, in a direction of 60 degrees W of N
<span>Jane goes a magnitude of 16 in a direction 30 degrees S of W </span>
<span>How I would solve this is to imagine that the started at (0,0) </span>
<span>And their walking represents vectors. </span>
<span>Ricardo: </span>
<span>X-coordinate = -27sin60 = 27sqrt(3)/2 = 23.383 </span>
<span>Y-coordinate = 27cos60 = 27/2 = 13.5 </span>
<span>So, after he walks, he is at point (-23.383, 13.5) </span>
<span>Jane: </span>
<span>X-coordinate = -16cos(30) = 16sqrt(3)/2 = 13.856 </span>
<span>Y-coordinate = -16sin(30) = 16/2 = 8 </span>
<span>So, after she walks, she is at point (-13.856, -8) </span>
<span>So, you have 2 points. </span>
<span>Use the distance formula to find their distance apart </span>
<span>Sqrt((-23.383+13.856)^2+(13.5+8)^2) = 23.516m </span>
<span>To find the direction, simply find the slope of the two points, and take the arc-tangent. </span>
<span>The slope = -9.527/21.5 = -0.443 </span>
<span>Take the tan^-1 of this, which is -23.899 degrees. </span>
<span>This basically translates to, Ricardo must walk 23.899 degrees E of S </span>
<span>They will be 23.518 m apart </span>
<span>Ricardo must walk 23.899 degrees East of South to get to Jane</span>
Answer: The correlation between all of these examples would be They are all earths natural energy balance. To maintain a constant global average temperature, all of the sun’s radiation that enters Earth’s atmosphere must eventually be sent back to space. The greenhouse effect plays a significant role in Earth's energy budget. With the natural greenhouse effect, the energy budget is balanced as thermal radiation is re-radiated towards the ground, trapping thermal energy and warming the Earth. However, with the greenhouse effect being enhanced by humans, the energy budget of the Earth is shifted to an imbalance. It is important to understand that a certain amount of energy being retained due to the greenhouse effect is necessary, but too much results in conditions that account for increased global temperatures and climate change.
Explanation:
Answer:
7.74 seconds
Explanation:
u = 25 m/s
h = - 100 m
Let it takes time t to hit the ground.
Use second equation of motion
Take positive sign as time can never be negative.
t = 7.74 s
Thus, the package takes 7.74 seconds to reach the ground.
