Answer:
Force applied by bull dozer is 3333.33 joules.
Explanation:
Answer: The net charge on the sphere is -5.9nC
Explanation:
The electric field outside the conducting solid sphere is given as:
E = (kq)/r^2
Here, q is the net charge on the sphere and r is the distance from the center of the sphere.
The net charge is calculated as follows;
q = Er^2/k
E = 2.7*10^3N/C
r = 14cm = 0.14m
k = 8.99*10^9Nm^2/C^2
q = (2.7*10^3)(0.14^2)/(8.99*10^9)
q = 5.9*10^-9C
= 5.9nC
As the electric field directed radially inward, the net charge on the sphere is negative.
Hence the net charge on the sphere is -5.9nC
Answer:
Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease
Answer:
kinetic energy of the object is 24 J
Explanation:
As we know that kinetic energy is given as
here we know that
m = 3 kg
v = 4 m/s
so we will have
so kinetic energy of the object is 24 J
