Answer:
v= - 4.507 i - 2.363 j
Explanation:
Given that
mc= 1490 kg
vc= 9.5 m/s ( - i)
mt= 1650 kg
vt = 6.4 m/s ( -j)
There is any external force so linear momentum will remain conserve.
Lets take final speed is v.
mc .vc + mt . vt = ( mc+mt) v
1490 x 9.5 ( - i) + 1650 x 6.4 ( -j) = ( 1490+1650) v
14,155 ( -i) + 10,560 ( - j) = 3140 v
v= - 4.507 i - 2.363 j
Answer: d
One thirty-sixth of
Explanation: Gravitational field or gravitational field strength obeys the inverse square law. The gravitational field is inversely proportional to the square of the earth distance. That is,
g = Gm/r^2
Where r = distance.
If weather satellite is placed in orbit six times farther away from the earth's centre, gravitational field will be one thirty-sixth of its initial value.
Therefore, the gravitational field experienced by the satellite in orbit is one thirty-sixth of the field that it experienced on the ground.

Answer: CONDENSER
Explanation:
CONDENSER is the component of the microscope that is found directly under the stage, and contains two sets of lenses that collect and concentrate light as it passes upward from the light source into the lens systems. The condenser increases the resolution of light.
A microscope is an instrument that is used in laboratory to examine objects that can't be viewed with the naked eye. This is possible with as it is designed with lenses that aids in magnification of the objects.
