Answer : The mass of cereal in two units are, 34.815 oz and 978.075 grams respectively.
Explanation :
As there are two systems for measuring the units which are English and Metric system.
The Metric System measured the things in meters, grams, liters, etc and adds prefixes like kilo, milli and centi to the count orders of the magnitude.
The English system measured the things in feet, inches, pounds, mile, etc.
As we are given the mass of cereal in 978 grams that means 987 grams is in metric unit. Now we have to convert metric unit into English unit.
Conversion factor used : (1 oz = 28.350 g)
As, 28.350 grams = 1 oz
So, 987 grams =
= 34.815 oz
As we are given the mass of cereal in 34.5 oz that means 34.5 oz is in metric unit. Now we have to convert metric unit into English unit.
Conversion factor used : (1 oz = 28.350 g)
As, 1 oz = 28.350 grams
So, 34.5 oz =
= 978.075 grams
Therefore, the mass of cereal in two units are, 34.815 oz and 978.075 grams respectively.
Answer:
Its resultant velocity will be 320 km/h.
Explanation:
The tail wind is called the wind that brings greater speed to an airplane, because it has the same direction as the airplane and, therefore, contributes a positive force to the force that the airplane's engines print on it.
Thus, a tailwind adds its speed to the speed of the plane, developing a resulting speed higher than that marked on the air transport speedometer.
In the case, given that the speed of the plane is 240 km / h and the tail wind is 80 km / h, the resulting speed will be 320 km / h.
Explanation:
Given that,
Mass of thee pool ball, m = 3 kg
Initial speed of the ball, u = -4.3 m/s
Impulse experienced by thee ball, J = -4 N-s
To find,
Speed of the object after impulse occurs and its direction.
Solution,
Let left side is negative and right side is positive. So, the change in momentum or the impulse is given by the following expression as :
v = -5.663 m/s
So, the speed of the object is 5.663 m/s and it is towards left.
