Answer:
The normal force will be "122.8 N".
Explanation:
The given values are:
Weight,
W = 100 N
Force,
F = 40 N
Angle,
θ = 35.0°
As we know,
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
⇒ 
By definition, the density of an object is given by:

Where,
M: mass of the object
V: volume of the object
Since the mass and volume of an object are numerical values greater than zero, then it follows that:

It is important to respect the units of each measure.
For this case we can use the grams for the mass and cubic centimeters for the volume.
Answer:
A possible value for density is given by:

Answer:40kg m/s
explanation: momentum =mass x velocity
Answer:
a. 8000 N/C or 8000 V/m
b. Incomplete question
Explanation:
a. The electric field, E, is the ratio of the potential difference,V, to the separation distance, d.
V = 360 V
d = 45 mm = 0.045 m

b. The force on a charge in an electric field is the product of the field and the charge.

With the charge, q, known, the force can be calculated.
Answer:
Las fuerzas se representan dibujando flechas sobre el cuerpo en el que actúan, por ejemplo, la fuerza que se aplica al empujar un barril. ... Para obtener la fuerza resultante, puede aprovecharse la representación gráfica mediante flechas.
