Answer:
a. Gamma ray, microwaves, infrared
Answer:
0.000064 cubic meters.
Explanation:
Given the following data;
Length of side = 4 centimeters
Conversion:
100 centimeters = 1 meters
4 cm = 4/100 = 0.04 meters
To find the volume of cuboid;
Mathematically, the volume of a cuboid is given by the formula;
Volume of cuboid = length * width * height
However, when all the sides are equal the formula is;
Volume of cuboid = L³
Volume of cuboid = 0.04³
Volume of cuboid = 0.000064 cubic meters.
The answer is option A.
Centripetal force is always directed towards the centre and does not change the speed of the body,but there is a change in the direction.
Answer:
<em>The final velocity of the student and the boat is 1.66 m/s</em>
Explanation:
<u>Law Of Conservation Of Linear Momentum
</u>
The total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and velocity v is P=mv. If we have a system of bodies, then the total momentum is the sum of them all
Let's call 
the mass of the physics student, 
the mass of the boat, 
the initial speed of the student, 
the initial speed of the boat, 
the final speed of both, assumed common since they keep joined after the jump. Applying the law of conservation of momentum, being 
the initial and final momentum of the system, we have
Solving for
The final velocity of the student and the boat is 1.66 m/s
