Answer:
P = 30000 [kg*m/s]
Explanation:
Momentum in physics is defined as the product of force in the given time interval. In this way, it can be expressed by means of the following equation.
where:
P = momentum [kg*m/s]
F = force = 6*10⁴ [N]
t = 0.5 [s]
Now replacing:
![P=6*10^{4}*0.5\\P=30000[kg*m/s]](https://tex.z-dn.net/?f=P%3D6%2A10%5E%7B4%7D%2A0.5%5C%5CP%3D30000%5Bkg%2Am%2Fs%5D)
Answer:
Explanation:
Given:
Initial θ = 0 rad (from rest)
Final θ = 14.3 rad
Time, t = 5 s
B.
Angular velocity, w = dθ / dt
= (14.3 - 0)/5
= 2.86 rad/s
A.
Acceleration, ao = dw/dt
Initial angular velocity, wi = 0 rad/s (from rest)
Final angular velocity, wf = 2.86 rad/s
a = (2.86 - 0)/5
= 0.572 rad/s^2
Answer:
Magnetic field is in south west direction .
Explanation:
Let us represent various direction by i , j, k . i representing east , j representing north and k representing vertically upward direction .
magnetic field is represented vectorially as follows
B = B₀ ( - i - j )
In the first case velocity of electron
v = v k
Force = q ( v x B )
= -e [ vk x B₀ ( - i - j ) ]
= evB₀ ( j -i )
Direction of force is north -west .
In the second case velocity of electron
v = vj
Force = -e [ vj x B₀ ( - i - j ) ]
= - evB₀ k
force is downward
In the third case, velocity of electron
v = v( -j +i )
Force = -e [ v( -j +i ) x B₀ ( - i - j ) ]
= 2 evB₀ k
Force is upward.
Pascals = N/m2
so it is the same unit
the answer is 70 Pa
Answer:
0.235 nC
Explanation:
Given:
= the magnitude of electric field = 
= the magnitude of electric force on each antenna = 
= The magnitude of charge on each antenna
Since the electric field is the electric force applied on a charged body of unit charge.
Hence, the value of q is 0.235 nC.
