Answer:
27 cm squared
Explanation:
have a good rest of ur day
You draw 3 circles around the stations with the size of the circle equal to the distance from the earthquake. Then you simply find where the edge circles all overlap.
The time of motion of the 5 kg object will be the same as 1 kg since both objects are dropped from the same height.
The given parameters;
<em>Mass of the first object, m1 = 1 kg</em>
<em>Mass of the second object, m2 = 5 kg</em>
The final velocity of the objects during the downward motion is calculated as follows;
The time of motion of the object from the given height is calculated as;
The time of motion of each object is independent of mass of the object.
Thus, the time of motion of the 5 kg object will be the same as 1 kg since both objects are dropped from the same height.

When supernova explodes
because of the collapsing cores, the core itself will become a neutron star or
a white dwarf without undergoing any kind of explosive transformation. The white
dwarf stars can also become supernova if they orbit another star in a binary
system and steal material from their companion. In addition, the end state of a
star, whether it will explode as a supernova become a black hole.
Answer:
a)P= -4800 i
b)F= 0
Explanation:
Given that
r = (4570-160 t) i + 2930 j + 130 k
We know that velocity is rate of change of the space vector.
V= dr/dt
r = (4570-160 t) i + 2930 j + 130 k
dr/dt= -160 i + 0 + 0
dr/dt= -160 i
V= -160 i
It means that velocity is in only x-direction
We also know that acceleration is the rate of change of velocity .
a= dV/dt
V= -160 i
dV/dt=0
So we can say that acceleration is zero.
a= 0
From Second law of Newton'
Force = Mass x acceleration
F= 300 x 0
F= 0
We know that linear momentum P
P = m V
Given that m= 300 kg
P = 300 x (-160 i)
P= -4800 i
