Answer:
If x-rays get in touch with our body tissues, they create a picture of a metal film. The high energizing rays are unable to penetrate soft tissue, such as skin and organs and travel through the laser. The places where the x-rays pass soft tissues are Black areas of an X-ray.
Answer:90.3 kg
Explanation:
Given
Mass of astronaut
Initial velocity of canister
Final velocity of canister
Final speed of Astronaut
let M be the mass of canister
As there is no external force therefore we can conserve momentum
The speed of a chemical reaction is affected by four factors: enzymes, concentration, temperature, particle size, and the presence of a suitable catalyst.
Answer:
Distance, S = 13m
Explanation:
Given the following data;
Initial velocity, u = 4m/s
Final velocity, v = 9m/s
Time, t = 2 seconds
To find the distance, S;
First of all, we would determine the acceleration of the shark.
Acceleration = (v - u)/t
Acceleration = (9 - 4)/2
Acceleration = 5/2
Acceleration = 2.5m/s²
Now, to find the distance we would use the second equation of motion
S = ut + ½at²
Substituting into the equation, we have
S = 4(2) + ½*2.5*2²
S = 8 + 1.25*4
S = 8 + 5
Distance, S = 13m
Think of this as a parabola, there is no resistance but what comes up must come down, which would represent gravity, therefore your answer would be A.
