Answer:
<h2>92.86 kg </h2>
Explanation:
lThe mass of an object given only it's force and acceleration can be found by using the formula
f is the force
a is the acceleration
From the question
f = 195 N
a = 2.1 m/s
We have
We have the final answer as
<h3>92.86 kg</h3>
Hope this helps you
Answer: Its the last one: The position of the block will change
Explanation: Since the forces are unbalanced, one side of the block will be stronger, therefore making the block move.
Answer:
1331.84 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity = 0
s = Displacement = 490 km
a = Acceleration
g = Acceleration due to gravity = 1.81 m/s² = a
From equation of linear motion
The speed of the material must be 1331.84 m/s in order to reach the height of 490 km
Answer:
The Kf (Freezing Point Depression Constant) is been affect by freezing point among many other factor now using tap water for this experiment would mean that there would be salt present in the solution in that tap water is usually added fluoride which would react with the natural potassium present in the water to form a salt this salt would depress the freezing point of the water hence the value of Kf would be bigger that the actual value
Explanation:d
