Answer
Correct Answer is D( Marie Sklodowska-Curie)
Explanation
Marie Curie is known for her contributions such as the discovery of Radium and other key elements help us out every day, especially when getting an x-ray.
Marie Curie worked with her husband Pierre Curie and received the Nobel Prize in 1903 for their research of discovery of radium. Marie curie and Pierre Curie published a research paperin which they mentioned the processes they have used to isolate radium. Marie Curie works described the effects of radium on living organisms. Marie Curie showed it could damage tissue, and this discovery was used against cancer and other diseases.
Answer:
15Ns
Explanation:
Given parameters:
Mass of the object = 10kg
Force impact = 5N
Time of action = 3s
Unknown:
Impulse applied on the object = ?
Solution:
Impulse is the force that acts on object within a period of time.
Mathematically;
Impulse = Force x time
Now insert the parameters and solve;
Impulse = 5 x 3 = 15Ns
Answer:
because you are taking longer and faster strides
Explanation:
Answer:
A
Explanation:
The equation of power is defined as Power = Workdone/Time Taken
And workdone = Force x Distance so using these equations we get they workdone is, 200x 10 = 2000Nm.
Dividing workdone with time will yield power, 2000 ÷ 8 = 250 Nm/s = 250W.
