Answer:
Explanation:
simple, just use F = ma
assume that the acceleration is any positive value <em>a</em>
The force F must accelerate both sleds
F = (2m + m)<em>a</em>
The force T must accelerate the rear sled
T = m<em>a</em>
T/F = m<em>a</em>/3m<em>a</em> = 1/3
Answer:
Below
Explanation:
To find the force needed to move an object, you can use this formula :
force = (mass)(acceleration)
Plugging our values in...
force = (400g)(3 m/s^2)
= 1,200 Newtons
We can see how this works for the previous answers :
force = (100g)(3 m/s^2)
= 300 Newtons and so on....
Hope this helps! Best of luck <3
The answer is B. The nuclei of elements.
Answer:
Power, P = 30 W
Explanation:
We have,
Voltage drop of a circuit is 60 V
Resistance of the resistor is 120 ohms
Current across the circuit is 0.5 A
It is required to find the power conducted by the resistor. Power conducted by a resistor is given by :
V and I are voltage and current
So, the power conducted by the resistor is 30 watts.
What Newton discovered is that gravity extends throughout the universe.
<h3>What is gravity?</h3>
The term gravity refers to the force that acts on a body in the universe. It is gravity that makes an object to fall when it is thrown up. The force of gravity acts on every object in the universe and it extends through the universe.
Humans have always known about gravity when they fall from a height and when they threw things up. However, human did not know that gravity extends throughout the universe.
Thus, what Newton discovered is that gravity extends throughout the universe.
