Answer:
3740N
Explanation:
The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below. If the net force acting on an object is zero, then the object is not accelerating and is in a state that we call equilibrium.
The formula for force is force = mass x acceleration.
To find mass, simply divide the force by the acceleration
acceleration=1.1m/s²
Mass=4500−760=3400N
Therefore, Mass x acceleration
=1.1m/s²x3400=3740N
Our skelotns would have to change as, they require less pressure and so on. Even now we can only survive a certain time in space.
Answer:
(A). The horizontal initial velocity is 25 m/s.
(B). The vertical initial velocity is 43.3 m/s.
(C). The velocity component is
Explanation:
Given that,
Initial velocity = 50.0 m/s
Angle = 60°
We need to calculate the component of velocity
Using formula of component
(A). Horizontal initial velocity
Put the value in to the formula
(B). Vertical initial velocity
Put the value in to the formula
The velocity component is
Hence, (A). The horizontal initial velocity is 25 m/s.
(B). The vertical initial velocity is 43.3 m/s.
(C). The velocity component is
Answer:
Explanation:
Given
zero vertical displacement
suppose \theta is the inclination angle and u is the initial velocity
considering horizontal motion
range is given by
where t is the time of flight
Now consider vertical motion
a=acceleration
for zero displacement y=0
substitute the value of t in Range
for maximum vale of must be equal to 1
i.e.
Answer:
A) If you halve the wavelength, the electromagnetic radiation energy will double.
B) The energy of the electromagnetic radiation will halve if you halve the wavenumber.
C) When the frequency of the light is doubled, its energy will double.
Explanation:
The function for the light frequency is given as
The energy supplied to each electron is doubled by halving the wavelength, nearly doubling its kinetic energy by two after it is free from the metal. It is important to remember that for a given period of time, the number of electrons ejected will remain constant.
