Answer:
Explanation:
The weight of some mass is defined as the product of mass by gravitational acceleration. In this way using the following formula we can find the weight.
where:
w = weight [N]
m = mass = 0.06 [kg]
g = gravity acceleration = 10 [N/kg]
Therefore:
By Hooke's law we know that the force in a spring can be calculated by means of the following expression.
where:
k = spring constant [N/m]
x = deformed distance = 6 [cm] = 0.06 [m]
We can find the spring constant.
Since we use the same spring on the moon and the same mass, the constant of the spring does not change, the same goes for the mass.
Since this force is equal to the weight, we can now determine the gravitational acceleration.
Yes I'm pretty sure you can
Answer:
Initial velocity of first cart will be 0.5 m /sec
Explanation:
We have given mass of the cart
Its collides with other cart of mass
Let the initial velocity of cart 1 is
As the car 2 is initially at rest so = 0 m/sec
After the collision velocity of first cart is 0.25 m/sec
So = 0.25 m/sec and velocity of second cart is 0.50 m /sec
So = 0.5 m/sec
From conservation of momentum we know that
= 0.5 m /sec
So initial velocity of first cart will be 0.5 m /sec
The speed of light (electromagnetic radiation) is equal to 299 792 458
m / s or 3x10^8 m/s in scientific notation.
So with this information, we could now look for the
distance. Solution:
Take note that μs means microseconds.
Speed of light * microseconds travelled * actual amount of microseconds
(3x10^8 m/s) (45.0 μs) (1x10^-6 s/μs) = 13,500 m.
