Identify the correct statement for measuring weight using a beam balance:
-
When near the actual weight, weights should be tried in decreasing order
-
The beam should be lowered before adding or removing weights from the pan
-
Both A and B are true
-
Neither A nor B is true
Precautions in using a beam balance:
1. The weight should be replaced into the weight box after weighing.
2. Wet and hot objects should not be kept on the plan.
3. When near the actual weight ,weights should be tried in decreasing order.
4. The beam should be lowered before adding or removing weights from the pan.
5. The lever should be turned gently ,in order to prevent the knife edges from chipping.
Identify the wrong way of handling a beam balance:
-
The lever should be turned fast in order to prevent the knife edges from chipping
-
The weight should be replaced into the weight box after weighing
-
Wet and hot objects should not be kept on the plan
-
When near the actual weight ,weights should be tried in decreasing order
1. The weight should be replaced into the weight box after weighing.
2. Wet and hot objects should not be kept on the plan.
3. When near the actual weight ,weights should be tried in decreasing order.
4. The beam should be lowered before adding or removing weights from the pan.
5. The lever should be turned gently in order to prevent the knife edges from chipping.
While using a beam balance, if we do not turn the lever gently,
-
the knife edges will be chipped
-
the lever will break
-
the beam will break
-
nothing will happen
The lever should be turned gently in order to prevent the knife edges from chipping.
Wet objects should not be kept on the pan as :
-
the weight measured will be more than actual
-
the weight measured will be less than actual
-
the weight measured will be same as actual
-
the pan may break down
If a wet object is kept on the pan of a beam balance, the weight measured will be more than usual.
The weights in a beam balance should not be carried with bare fingers
-
to avoid change in weight due to moisture and dust
-
to avoid change in weight due to chemical reactions
-
just to make use of the forceps
-
to avoid dropping of weights on the pan
The weights for a beam balance should be carried with forceps. Those should not be carried with bare fingers to avoid the change in the weight due to the presence of moisture and dust particles.
Fill in the blank:
In a beam balance, the beam should be ______ before adding or removing weights from the pan.
-
raised
-
lowered
-
held horizontal
-
held vertical
The beam, in a beam balance, should be lowered before adding or removing weights from the pan.
Mark the correct statement regarding to beam balance.
-
The physical balance consists of a light and rigid beam of brass, a metallic pillar, a wooden base, two pans, a metallic pointer, and an ivory scale
-
The device is enclosed in a box to avoid the effect of wind
-
A weight box containing standard weights comes with the balance
-
All of the above
The physical balance consists of a light and rigid beam of brass, a metallic pillar, a wooden base, two pans, a metallic pointer, and an ivory scale.
The device is enclosed in a box to avoid the effect of wind. A weight box containing standard weights comes with the balance. The mass of a body is found by placing the body in one pan, placing some standard weights in the other, and then calculating it from the standard weights placed and the resting point of the pointer.
When we are near to getting the actual weight in a beam balance, standard weights should be tried in :
-
decreasing order
-
increasing order
-
either increasing or decreasing order
-
at random
1. The weight should be replaced into the weight box after weighing.
2. Wet and hot objects should not be kept on the plan.
3. When near the actual weight ,weights should be tried in decreasing order.
4. The beam should be lowered before adding or removing weights from the pan.
5. The lever should be turned gently ,in order to prevent the knife edges from chipping.
Objects measured in beam balance should be
-
hot and wet
-
hot but not wet
-
wet but not hot
-
neither hot nor wet
