Answer:
The gravitational acceleration is 5.03 m/s² on the surface of the planet.
Explanation:
Frequency:
The number of complete oscillation per unit second is called frequency.
Angular frequency:
Angular frequency is the product of the oscillation frequency and the angle thought which the object moves.
Angular velocity
Given that,
Number of oscillation= 247, time= 793 s, length of the pendulum=1.31 m
Hz.
Angular velocity
=1.96 rad/s
We know that,
g= gravitational force of the planet
= length of the pendulum
= angular velocity
m/s²
= 5.03 m/s²
The gravitational acceleration on the surface of the planet is 5.03 m/s².
Systolic pressure is measured when the heart beats and the muscles are contracted. Diastolic Pressure is to measure the pressure on blood vessels when the muscles of the heart are relaxing.
<h3><u>
Explanation:</u></h3>
Blood pressure is the pressure that is put on blood vessels and the heart muscles when it is pumping blood. The blood pressure can be categorized as high and low. Both of them come with medical consequence and require attention and treatment.
The measurement of blood pressure contains two values:
Systolic Blood Pressure: When the blood is being pumped through the heart, a certain amount of pressure is applied on the arteries and contracted muscles of the heart. The pressure is measured to check if a person has a risks of heart strokes or attacks as well as kidney failures.
Diastolic Blood Pressure: When the blood is being pumped through the heart, a certain amount of pressure is applied on the blood vessels when the muscles are relaxing. The pressure is measured to prevent lack of oxygen that may cause severe damage to brain, heart and normal functionality of the individual.
Answer:
It will increase
Explanation:
The kinetic energy is the energy possessed by a moving object and is given by:
KE =
where m = mass of the object and v = velocity of the object.
It does means that the more the mass of an object in motion, the more the kinetic energy of the object if there are no opposing force such as friction. Also, the more the kinetic energy of the object, the more the speed of that object.
<em>Hence, as the weight of the cart increases by addition of groceries, the kinetic energy increases and the speed also increases as it moves along the frictionless surface.</em>
Ek = 1/2 m v^2
Ek = 1/2 × 60 × 2^2
Ek = 1/2 × 60 × 4
Ek = 120 J
the kinectic energy is 120 J
Answer:
(a) 1.716 MeV
(b) 0.284 MeV
(c)
Solution:
As per the question:
Energy of the scattered neutron, E = 2 MeV =
Atomic no. of
Now,
To calculate the Kinetic Energy of the scattered neutron,
where
Therefore,
(a) The energy of the scattered neutron is: 2 MeV - 0.284 MeV = 1.716 MeV
(b) The recoil energy of the nucleus is 0.284 MeV
(c) The angle of the recoil of the nucleus is
