F = ma (force = mass x acceleration)
So the car’s mass affects the amount of force, changing how it would roll down a ramp, I think.
Answer:
F' = 162 units
Explanation:
The gravitational force of attraction between the two objects is given by Newton's Gravitational law through the following formula:
where,
F = gravitational force = 18 units
G = Gravitational Constant
m₁ = mass of object 1
m₂ = mass of object 2
r = distance between objects
Therefore,
Now, if we change the value of distance to one-third of original value, then:
r' = r/3
using eqn (1):
F' = 9(18 units)
<u>F' = 162 units</u>
any two uses of good conductor of heat are
aluminium, cooper, metal are good conductor of heat and they are used for making utensils.
gold, silver, are also good conductor of heat they are used for making jewelleries.
Answer:
k = 39.2 N / m
Explanation:
The 200 g block is accelerated by the force of friction between the blocks. Let's use Newton's second law
N- W = 0
N = W
fr = ma
μ N = ma
μ mg = ma
a=μ g
Let's look for the acceleration of the largest block that has oscillatory movement
x = A cos (w t)
A = 0.05 m
The maximum acceleration is cos wt = ±1
a = A w2
a = A k / m
We substitute and calculate
μ g = A k / M
k = μ g M / A
The mass that performs the oscillation is the mass of the two bodies
M = m1 + m2
k = 0.2 9.8 (0.800+ 0.200) /0.05
k = 39.2 N / m
