Answer:
Resultant horizontal force = 143 N
Explanation:
Since the a gle is 30° northwest, then it means the resultant force will be horizontal and as such;
Resultant horizontal force = 165 * cos 30
Resultant horizontal force = 142.89
Approximating to a whole number gives;
Resultant horizontal force = 143 N
The correct answer is B. Measurable
Explanation:
The use of science to investigate a phenomenon implies using measurements and observations to better understand a phenomenon or test a hypothesis. Moreover, science focuses on natural phenomena that can be objectively studied through measurement instruments such as a thermometer, balance, hydrometer, etc.
In this context, for a phenomenon to be studied by science this needs to be measurable because the use of precise instruments as wells as numbers allow scientist to analyze and understand a phenomenon. Moreover, phenomena that depend on personal perspectives and cannot be measure is considered as non-scientific.
They both make a thing go faster and slower but the relationship is force.
Answer:
The magnitude and direction of the acceleration of the particle is
Explanation:
Given that,
Mass
Velocity
Charge
Magnetic field
We need to calculate the acceleration of the particle
Formula of the acceleration is defined as
We need to calculate the value of
Now, put the all values into the acceleration 's formula
Negative sign shows the opposite direction.
Hence, The magnitude and direction of the acceleration of the particle is
