Answer:
impulse will be equal to 1.969 N-s
Explanation:
We have given mass of the golf ball m = 60.8 gram = 0.0608 kg
Horizontal speed of the ball is v = 32.4 m/sec
We have to find the impulse of the golf ball
We know that impulse is equal to momentum of the object
So we have to find the momentum of the object
Momentum of the object is equal to product of mass of the object and speed of the object
So
As momentum is equal to impulse so impulse will be equal to 1.969 N-s
Answer:
As we know that science is based upon logic. So the scientific theories have a logical reasoning behind them. So considering that in mind, scientific hypothesis include the motion of sailing rocks by animals, wind, flowing water, magnetic field, humans and gravity. The motion of the rocks by ghosts, God and magic are not scientific theories as we can not prove them logicaly.
Explanation:
Answer:
3 outcomes
Explanation:
Since the sum must be less than 7, then one of them cannot be 7 because 7 + something > 7. Also the minimum number is 2 so one of them cannot be 5 either because 5 + 2 = 7 is not less than 7.
So the only options we have here is 2 and 4. The outcome of this is
(2,2) so 2 + 2 = 4 < 7
(2,4) so 2 + 4 = 6 < 7
(4,2) so 4 + 2 = 6 < 7
Note that (4,4) is not possible because 4 + 4 = 8 > 7
So 3 outcomes have a sum less than 7 and contain at least one even number
Answer: The ratio of carnivorous species to all mammal species is 1:20
Explanation:
250:5000 = 250/250 = 1
250:5000 = 5000/250 = 20
Answer = 1:20
