Using the same antenna. Now he doesn't know if it was the antenna that caused the change in reception. so he wasn't only measuring the reception in his house he was measuring it based on different antennas
Answer:
Why are continental rises and abyssal plains relatively rare in the Pacific? This is because the extensive system of trenches along the active margins of the Pacific, trap much of the sediments flowing off the continents, preventing them from building the broad, flat abyssal plains typical of the Atlantic ocean basins.
Answer:
move at constant velocity.
Explanation:
Newton's first law (also known as law of inertia) states that:
"when the net force acting on an object is zero, the object will keep its state of rest or if it is moving, it will continue moving at constant velocity".
In the case of the probe, friction in deep space is negligible, therefore when the engine is shut down, there are no more forces acting on the probe: the net force therefore will be zero, so the probe will move at constant velocity.
Answer:
The weight lifter would not get past this sticking point.
Explanation:
Generally torque applied on the weight is mathematically represented as
T = F z
To obtain Elbow torque we substitute 4000 N for F (the force ) and 2cm
for z the perpendicular distance
So Elbow Torque is ![T_e= 4000 * 0.02](https://tex.z-dn.net/?f=T_e%3D%204000%20%2A%200.02)
![= 80Nm](https://tex.z-dn.net/?f=%3D%2080Nm)
To obtain the torque required we substitute 300 N for F and 30cm ![=\frac{30}{100} = 0.3 m](https://tex.z-dn.net/?f=%3D%5Cfrac%7B30%7D%7B100%7D%20%3D%200.3%20m)
So the Required Torque is ![T_R = 300 *0.3](https://tex.z-dn.net/?f=T_R%20%3D%20300%20%2A0.3)
![=90Nm](https://tex.z-dn.net/?f=%3D90Nm)
Now since
it mean that the weight lifter would not get past this sticking point
