Answer:
The second student with mass 70kg has more momentum
Explanation:
Using the formula:
p = m × v
Where;
p = momentum (kgm/s)
m = mass (kg)
v = velocity (m/s)
According to this question, two students are running in a cross country race.
Student 1 has the following; m = 60kg, v = 7m/s
Student 2 has the following; m = 70kg, v = 7m/s
Using p = mv
Student 1, p = 60 × 7 = 420 kgm/s
Student 2, p = 70 × 7 = 490 kgm/s
From the result of the above calculations, student 2 with mass 70kg has more momentum.

Answer:
The correct answer is GAMMA RADIATION.
Explanation:
Electromagnetic waves are waves that are created as the result of the interaction between the magnetic and the electric field. Gamma ray is a type of electromagnetic wave, it has the shortest wavelength compare to other electromagnetic waves, thus, it has high penetrating power. Gamma ray is an ionizing radiation, which can be a source of biological hazard.
