From the question we are told that:
Period
Trial 1
Spring constant
Period
Mass
Trial 2
Period
Generally the equation for Spring Constant is mathematically given by
\mu=\frac{4 \pi^2 M}{T^2}
Since
Therefore
Answer: The spinning of Earth's outer core causes the lithosphere to break into individual plates and collide with each other.
Earth's surface forms because of this reason:
The spinning of Earth's outer core causes the lithosphere to break into individual plates and collide with each other.
Answer:
k1 + k2
Explanation:
Spring 1 has spring constant k1
Spring 2 has spring constant k2
After being applied by the same force, it is clearly mentioned that spring are extended by the same amount i.e. extension of spring 1 is equal to extension of spring 2.
x1 = x2
Since the force exerted to each spring might be different, let's assume F1 for spring 1 and F2 for spring 2. Hence the equations of spring constant for both springs are
k1 = F1/x -> F1 =k1*x
k2 = F2/x -> F2 =k2*x
While F = F1 + F2
Substitute equation of F1 and F2 into the equation of sum of forces
F = F1 + F2
F = k1*x + k2*x
= x(k1 + k2)
Note that this is applicable because both spring have the same extension of x (I repeat, EXTENTION, not length of the spring)
Considering the general equation of spring forces (Hooke's Law) F = kx,
The effective spring constant for the system is k1 + k2
0.17m/s²
Explanation:
According to newtons second law "the force on a body is depends on its mass and acceleration"
Force = mass x acceleration.
The more the mass and acceleration, the more the force a body possess.
Given that the acceleration of the body is 0.33m/s²
Force = 0.33 x mass
If the force on the body is halved, the acceleration will also be halved;
i.e:
Force = F
= 0.33 x mass
F = x 0.33 x mass
F = 0.17 x mass
Force = acceleration x mass
Acceleration is 0.17m/s²
