Answer:
Object A will have greater acceleration.
Step-by-step explanation:
Given that,
The mass of object A = 50 kg
The mass of object B = 75 kg
They were pushed with the same amount of force.
We know that, the force acting on an object is given by :
F = ma
Here F is same for both mass
Mass and acceleration have inverse relation. It means the object whose mass is less will have greater acceleration. Hence, the acceleration is greater for object A.
scientist A dissolved 1 kg of salt in 3 litres.
scientist B dissolved 20 pounds of slat in 7 pint of water.
we know that 1 pound =0.543 g
20 pounds=9.07 kg.
1 pint=0.5 litres
so 7 pints =3.5 litres
so dissoving 1 kg of salt in 3 litres of water and 9.07 kg in 3.5 litres of water
we know that for concentration kg/l units is used .
for A= 1/3=0.33kg/l
and B=9.07/3.5=2.59 kg/l.
so scientist A has prepared more concentrated solution .
If you are looking for x then it is X = 18
4b + 6 - (2b + 2*3)
4b + 6 - (2b +6)
4b + 6 -2b - 6 (negative distributes)
ans: b
<h2>Answer:
81
Step-by-step explanation:
The median of data not grouped is the middle number after arranging the data is either ASCENDING OR DESCENDING order. Arranging these states HIGH TEMPERATURES in ascending order, we have:
72, 78, 79, 81, 81, 82, 84, 88, 88
The middle number there is 81 </h2>
