Answer:
<em>The net force that acts on the sailboat has a magnitude of 217 N and is applied at an angle of 64° north of east.</em>
Explanation:
<u>Mechanical Force</u>
The second Newton's law states the net force exerted by an external agent on an object of mass m is:
Where is the acceleration of the object. Note both the force and the acceleration are vectors. The relationship between them is the mass, a scalar.
This means the net force and the acceleration have the same direction.
The sailboat has a mass m= 350 Kg and moves at a=0.62 m/s^2. The magnitude of the net force acting on the boat is:
As stated above its direction is the same as the acceleration, thus:
The net force that acts on the sailboat has a magnitude of 217 N and is applied at an angle of 64° north of east.
Answer:
it will travel 69 m long consuming. it is totally wrong
2Na⁺ + CO₃²⁻ -> Na₂CO₃- the molecular formula for sodium carbonate
Ca²⁺ + 2NO₃⁻ -->Ca(NO₃)₂ - formula for calcium nitrate -
Ca²⁺ + CO₃²⁻ --> CaCO₃ - it forms calcium carbonate with formula
Na⁺ + NO₃⁻ -->NaNO₃ -formula for sodium nitrate -
the balanced chemical equation for the reaction is;
Na₂CO₃(aq) + Ca(NO₃)₂(aq) --> CaCO₃(s) + 2NaNO₃(aq)
correct answer is 4
A- sulfur oxide
B- carbon monoxide
The speed of the falcon is 144 km/h
Explanation:
The speed of a body is a scalar quantity telling how fast the object is moving, without giving any information about its direction.
It can be calculated as:
where
d is the distance covered
t is the time taken
In this problem, the falcon has a speed of
We want to convert it into km/h. Let's keep in mind that:
1 km = 1000 m
1 h = 3600 s
Therefore, we convert as follows:
