Answer:
acceleration of the balloon is 11.4 m/s²
and
The instruments accelerate downwards at 9.8 m/s²
Explanation:
given data
mass = 5 kg
force = 106 N
acceleration of gravity = 9.8 m/s²
to find out
the acceleration of the balloon and the instruments
solution
we find weight of the instruments that is
weight W = mg
here m is mass and g is acceleration of gravity
W = 5 ×9.8
weight W = 49 N
and
so net upward force on the instruments is
net upward force F = 106 - 49
net upward force F = 57 N
and
The acceleration of the balloon is
Force = ma
57 = 5 a
a = 11.4 m/s²
acceleration of the balloon is 11.4 m/s²
and
The instruments accelerate downwards at 9.8 m/s²
Answer:
The slope of the line is zero
The object is at rest
Explanation:
The graph position vs time of an object represents the position of the object measured at different times.
The slope of this graph is given by:
where
is the increment in the y-variable
is the increment in the x-variable
However, we have that:
corresponds to 
, the change in position of the object
corresponds to the change in time,
Therefore, for a position-time graph the slope of the graph corresponds to the velocity of the object:
An object having a flat line on a position-time graph has a line with slope zero: therefore, its velocity is zero, and this means the object is at rest.
It should be C
Explanation: Science is what you have to know and it’s not all about making cures and other stuff, if you should learn about our natural world.
hope this helps!
Answer:
1530*5.95/2
Explanation:
the waves traverse the depth twice before being received
time to reach the bed must be 5.95/2
hence depth = speed*time
I believe it's D, but I'm not entirely sure.
