Answer:
6 kg
Step-by-step explanation:
Given is weight of an object directly varies with the mass of the object .
Let the constant of proportionality be k
So,
Weight = K×(mass of the object)
For an object , weight = 45 N
mass = 9 kg
So , 45 = K×9
K = 5.
Now, for the other object ,
Weight = 30 N. K = 5 (as obtained above)
So, 30 = 5×(mass of the object)
mass of the object = 6 kg.
Answer:
Step-by-step explanation:
You divide 7.42 / 1.75 = the answer is 4.24
Answer:
the answer is A 3 to 2
Step-by-step explanation:
but if it's wrong I'm sorry but if it's right I'm happy for you
Step-by-step explanation:
anyway, without any further information about ground consistency, friction and stuff, we have to assume ideal circumstances.
so, the same energy that made the ball flying through the air makes it also bounce or roll across the ground carrying it exactly the same distance at the same time.
the distances with an ideal, reflective ground will be the same.
it is the same energy released with the same inertia.
Answer:
Mean = sum of all elements/number of elements
= (7.5 + 10.5 + 5 + 4.5 + 3.5 + 7.5 + 4 + 10 + 7.5 + 5)/10
= 6.5
=> Option C is correct
Hope this helps!
